NVIDIA Forms 37-Member Open Secure AI Alliance and Open-Sources NOOA Framework

NVIDIA Forms 37-Member Open Secure AI Alliance and Open-Sources NOOA Framework

Jul 27, 2026 AI Security / Software Security
NVIDIA and 36 other organizations have formed the Open Secure AI Alliance to develop and share open technologies, techniques, and tools for securing software and artificial intelligence (AI) agents. The 37-member group spans cloud, security, enterprise software, and AI companies, including Microsoft, Cisco, Cloudflare, CrowdStrike, Hugging Face, IBM, Palo Alto Networks, Red Hat, and the Linux Foundation. Its stated scope covers the full agent stack, including identity, permissions, isolation, guardrails, logs, model formats, multi-model scanning, and secure coding workflows. The pitch is that cyber defenders need AI models they can read, change, and run on their own hardware, not only closed systems reached through a vendor's application programming interface (API). The launch also brings its first named technical contribution: NVIDIA-labs OO Agents (NOOA) , an Apache 2.0 research framework designed to make agent behavior easier to test, trace, audit, and govern. The laun...
Public Exploit Released for Patched vBulletin Pre-Auth Code Execution Flaw

Public Exploit Released for Patched vBulletin Pre-Auth Code Execution Flaw

Jul 27, 2026 Vulnerability / Website Security
Public exploit details released on July 27 show how an unauthenticated request can reach PHP's eval() function inside vBulletin and execute code on an unpatched forum server. The attack requires no account, administrative access, or interaction from another user. SSD Secure Disclosure lists vBulletin 6.2.1 and earlier, and 6.1.6 and earlier, as affected, but does not give a lower version boundary. vBulletin issued security patches for 6.2.1, 6.2.0, and 6.1.6 at the end of June and released the fixed version 6.2.2 on July 1, nearly four weeks before the exploit went public Administrators running self-hosted installations should apply the patch for their branch or upgrade to 6.2.2. vBulletin says its Cloud sites have already been patched against the flaw. SSD did not report active exploitation. As of July 27, 2026, no source had confirmed in-the-wild attacks, and CVE-2026-61511 was not listed in CISA's Known Exploited Vulnerabilities catalog. The company published an int...
n8n Sandbox Escape Lets Workflow Editors Run OS Commands as the n8n Process

n8n Sandbox Escape Lets Workflow Editors Run OS Commands as the n8n Process

Jul 27, 2026 Vulnerability / Enterprise Security
n8n has patched a high-severity expression-sandbox escape that could let an authenticated workflow editor execute operating-system commands on the server running the automation platform. Security Joes found the flaw while probing n8n's February fix for CVE-2026-27577 for another bypass. The affected ranges are <2.31.5 and >=2.32.0,<2.32.1 . n8n fixed the flaw in versions 2.31.5 and 2.32.1 . It tracks the issue as GHSA-gv7g-jm28-cr3m , rates it High with a CVSS 4.0 score of 8.7, and no CVE had been assigned as of July 27, 2026. Administrators should update rather than rely on n8n's interim guidance to restrict instance access and workflow editing to fully trusted users. The advisory describes those controls as incomplete, short-term mitigations. It lists no patched 1.x release and does not say whether n8n Cloud was affected. Exploitation requires a valid account with permission to create or modify workflows. It does not require action from another user. A succ...

GitHub Adds 3-Day Dependabot Cooldown to Limit Poisoned Package Adoption

GitHub Adds 3-Day Dependabot Cooldown to Limit Poisoned Package Adoption

Jul 27, 2026 Software Supply Chain / DevSecOps
GitHub has announced a new cooldown mechanism in Dependabot, allowing the tool to wait at least three days after a release is published before opening a pull request. "The cooldown configuration option in the dependabot.yml still controls the behavior, though, so you can choose a different cooldown parameter that fits your project," the Microsoft-owned subsidiary said . According to GitHub, the three-day cooldown default only applies to version updates, which are designed to keep software dependencies up-to-date. Security updates will continue to be pushed right away, permitting Dependabot to issue an alert and open a pull request to move the project to the patched version. With this update, the idea is to handle scenarios where a threat actor manages to push a poisoned version of a popular package, which then gets quickly pulled by downstream projects before that version is yanked from the registry. Although such trojanized packages are short-lived, the time period fo...
Fastjson 1.x RCE Vulnerability Targeted in Attacks With No Patched Available

Fastjson 1.x RCE Vulnerability Targeted in Attacks With No Patched Available

Jul 25, 2026 Vulnerability / Application Security
Security firms ThreatBook and Imperva say attackers are targeting a critical flaw in Fastjson, Alibaba's JSON library for Java. In affected Spring Boot applications, a malicious JSON request can execute code without authentication, with the privileges of the Java process. Tracked as CVE-2026-16723 , the vulnerability carries an Alibaba-assigned CVSS score of 9.0. The confirmed chain requires Fastjson 1.2.68 through 1.2.83, a Spring Boot executable fat-JAR, a network-reachable path that sends attacker-controlled JSON to an affected parser, and SafeMode left at its disabled default. AutoType can remain disabled, and no classpath gadget is required. As of July 25, Alibaba had not released a fixed Fastjson 1.x version. Organizations that cannot migrate immediately should enable SafeMode with -Dfastjson.parser.safeMode=true or use com.alibaba:fastjson:1.2.83_noneautotype . Alibaba lists migration to Fastjson2 as the long-term fix. Alibaba published its advisory on July 21 follo...
Researcher Publishes GitLab RCE PoC Letting Authenticated Users Run Commands as Git

Researcher Publishes GitLab RCE PoC Letting Authenticated Users Run Commands as Git

Jul 25, 2026 Vulnerability / Application Security
Security researchers at  depthfirst published working exploit code on July 24 for a GitLab flaw that GitLab patched six weeks earlier, on June 10. It runs commands as git on any self-managed 18.11.3 server that has not taken the update. Any authenticated user who can push to a project can run it. The attacker commits a crafted Jupyter notebook and opens its commit diff, which leaks a heap pointer. Enough of those and an automated probe can locate the libraries in memory. Two more notebooks then fire the payload. No administrator rights, no CI or runner access, no victim interaction, no access to anyone else's project. GitLab did not file the fix as a security fix. A review by The Hacker News found the Oj 3.17.3 bump listed under bug fixes in the June 10 patch release , not in the security-fix table. There is no CVE, no CVSS score, and no mention of the notebook-diff chain. Operators who triaged that release against the security table had no reason to treat it as urgent. ...
Bing Images Flaws Let Crafted SVGs Run Commands as SYSTEM on Microsoft's Servers

Bing Images Flaws Let Crafted SVGs Run Commands as SYSTEM on Microsoft's Servers

Jul 24, 2026 Vulnerability / Web Security
A crafted SVG submitted to Bing's image search ran commands as NT AUTHORITY\SYSTEM on Microsoft's production image-processing workers, and as root on the Linux machines in the same fleet. XBOW's testing got the same result on workers across different hosts and network ranges, so the problem sat in Bing's image tier, not on one bad machine. Microsoft issued two critical CVEs, CVE-2026-32194 and CVE-2026-32191, and rated both 9.8 on the CVSS scale. XBOW, the autonomous offensive security startup, found both and reported them privately. Bing users have no patch or mitigation to apply: Microsoft fixed both server-side before the advisories went out in March, and the records state there is "no customer action to resolve." Neither advisory recorded exploitation or public disclosure when they went up on March 19. XBOW published the exploit mechanics on July 23, after holding them back at Microsoft's request until the remediation had landed. What outlive...
Seeing AI Agents Is Not Enough. Security Teams Must Enforce What They Can Do

Seeing AI Agents Is Not Enough. Security Teams Must Enforce What They Can Do

Jul 24, 2026 Enterprise Security / AI Security
AI agent security is moving through a familiar maturity curve: adoption, then visibility, and finally, control. But what we've collectively discovered is that enforcing least privilege for AI agents is harder than we ever imagined. This is why there are so many approaches, from prompt filtering to identity-layer access controls. Where we've collectively landed is that understanding the intent of AI agents is essential to securing them. It's not easy, but it's the only path forward. Organizations approach this challenge with different levels of sophistication. For many, the current goal is simply to find the AI agents already operating across the business. That is a necessary first step. AI agents are appearing in SaaS platforms, developer environments, cloud workflows, customer support systems, productivity tools, and internal applications. Some are sanctioned, and others are not. But discovery alone isn't useful. AI agents are not passive; they reason, plan, c...
NodeBB Patches Eight AI-Found Flaws Exposing Admin Access and Private Chats

NodeBB Patches Eight AI-Found Flaws Exposing Admin Access and Private Chats

Jul 24, 2026 Web Security / Vulnerability
Eight security flaws in NodeBB went public on Wednesday, along with the code to exploit them. Aikido Security rates all eight as high severity and says its AI pentest agents found them in a six-hour review of the forum software's source code. Every version before 4.14.0 is affected. NodeBB has fixed them all, and administrators should be on 4.14.2. The simplest one takes a settings change. A regular forum member could point their homepage setting at the admin address, reload the page, and the admin dashboard opened for them. No password, no exploit code. The forum's own interface blocks that setting, but the block only ran in the browser and could be sidestepped. Most of what a member could then reach was read-only, including the error log and any user list an admin had exported, though they could also swap the site logo. Two more gave an attacker with no account at all access to things meant to be private. One let anyone claim to be any user and read private messages...
Claude Cowork Flaw Could Let AI Agent Escape Its VM and Access Mac Files

Claude Cowork Flaw Could Let AI Agent Escape Its VM and Access Mac Files

Jul 23, 2026 Vulnerability / Application Security
Cybersecurity researchers have uncovered a sandbox escape vulnerability in Anthropic's Claude Cowork that makes it possible to break out of the confines of a Linux virtual machine (VM) within which the agent runs to read or write files anywhere on the Mac. Accomplish AI, which shared details of the vulnerability with The Hacker News ahead of publication, said about 500,000 macOS users running local Cowork sessions were affected prior to it being patched. It has been codenamed SharedRoot . "We connected a folder to a fresh Claude Cowork session, sent one short message, and watched the agent escape the sandbox," Oren Yomtov, principal security researcher at Accomplish AI, said . "From inside the VM, it reached the host Mac and read and wrote files all over it, far outside the folder we'd connected, with no permission prompt anywhere." With this level of access, the agent can access any data stored on the Mac via the user's account, including SSH ke...
GitHub Cuts Public Bug Bounty Payouts, Moves Top Rewards to VIP Tier

GitHub Cuts Public Bug Bounty Payouts, Moves Top Rewards to VIP Tier

Jul 22, 2026 Vulnerability / DevSecOps
Beginning July 27, 2026, GitHub will cut public bug bounty payouts by at least half at every severity level. Critical findings will drop from $20,000-$30,000+ to a fixed $10,000, while its permanent invite-only VIP tier will pay $30,000 or more. Reports filed before that date, including those already in GitHub's growing triage queue, will retain the previous payout terms. GitHub said the changes are intended to reduce noise while giving established researchers faster responses, higher rewards, and closer access to its security engineering team. "You don't earn more by submitting more," the company said. "You earn more by submitting better." The public program is moving from flexible ranges to fixed payments: Low: $250, down from $617-$2,000 Medium: $2,000, down from $4,000-$10,000 High: $5,000, down from $10,000-$20,000 Critical: $10,000, down from $20,000-$30,000+ The Hacker News calculated that the new public rates are 50% lower f...
Adobe Acrobat Extension Flaw Let Malicious Sites Read WhatsApp Web Data

Adobe Acrobat Extension Flaw Let Malicious Sites Read WhatsApp Web Data

Jul 22, 2026 Vulnerability / Browser Security
Cybersecurity researchers have disclosed details of a now-patched vulnerability chain in the Adobe Acrobat Chrome extension that has over 314 million users, which, if exploited, could facilitate a silent hijack of a user's WhatsApp data. The shortcoming has been codenamed HermeticReader by Guardio Labs. It's officially tracked as CVE-2026-48294 (CVSS score: 7.4), with the vulnerability described as a case of universal cross-site scripting (UXSS)-class cross-origin data disclosure vulnerability. It affects all versions of the extension (ID: efaidnbmnnnibpcajpcglclefindmkaj ) prior to and including 26.5.2.2. Successful exploitation of the flaw can bypass the browser's same-origin policy and access data linked to the victim's session across origins. The only prerequisite is that it requires user interaction. A victim must be convinced into visiting a maliciously crafted URL or interact with a compromised web page that triggers the extension's vulnerable code ...
Hackers Exploit Windmill Flaw to Read Arbitrary Server Files Without Authentication

Hackers Exploit Windmill Flaw to Read Arbitrary Server Files Without Authentication

Jul 22, 2026 Vulnerability / Web Security
A high-severity security flaw impacting open-source developer platform Windmill has come under active exploitation in the wild, per VulnCheck. The vulnerability in question is CVE-2026-29059 (CVSS score: 7.5), a case of unauthenticated path traversal impacting Windmill's "get_log_file" endpoint ("/api/w/{workspace}/jobs_u/get_log_file/{filename}"). "The filename parameter is concatenated into a file path without sanitization, allowing an attacker to read arbitrary files on the server using ../ sequences," according to an advisory published by Windmill in March 2026. "The primary sensitive value exposed by this vulnerability is the SUPERADMIN_SECRET environment variable, readable via /proc/1/environ. When set, this secret can be used as a Bearer token to authenticate as a superadmin and execute arbitrary code through the job preview API." However, it's worth noting that SUPERADMIN_SECRET is not set by default, and for standalon...
OpenAI Says Its AI Models Escaped Sandbox, Targeted Hugging Face to Cheat Benchmark

OpenAI Says Its AI Models Escaped Sandbox, Targeted Hugging Face to Cheat Benchmark

Jul 22, 2026 AI Security / Cloud Security
OpenAI on Tuesday said a combination of its artificial intelligence (AI) models, including GPT-5.6 Sol and an "even more capable pre-release model," was behind the security incident that targeted Hugging Face's production infrastructure last week. The AI company said the models were operating with "reduced cyber refusals for evaluation purposes" that might otherwise limit their ability to conduct cyber attacks, adding it expects such incidents to "become more commonplace with the proliferation of increasingly cyber-capable models." Incidents like this may become more common. Subscribe, and we’ll alert you only when another major AI security story breaks. Describing it as an "unprecedented cyber incident" and one involving state-of-the-art cyber capabilities, OpenAI said it intends to conduct a thorough investigation in partnership with Hugging Face to get to the bottom of the matter. As part of an internal evaluation, the models...
Trojanized Newtonsoft.Json Fork Hides Game-Rigging Code in a Working Library

Trojanized Newtonsoft.Json Fork Hides Game-Rigging Code in a Working Library

Jul 22, 2026 Supply Chain Attack / Malware
Cybersecurity researchers have discovered a NuGet typosquat that's unlike the typical information-stealing malware distributed via package registries: usual info-stealers: it's designed to rig live game results on Digitain. The package, named " Newtonsoftt.Json.Net ," masquerades as the Newtonsoft.Json library and is a trojanized fork. Seven versions of the package have been published to the NuGet repository: 11.0.4, 11.0.5, 11.0.7, 11.0.8, 11.0.9, 11.0.10, and 11.0.11. The package has been downloaded about 1,200 times to date. The package has been unlisted by its owner MagicalPuff96, meaning it will not be surfaced via a search on NuGet. However, the artifacts are still available for download from the registry. "The trojan rigs Digitain, an online betting platform, and in later generations, exfiltrates rigged round results to an attacker-controlled server, utilizing the header X-Seq-ApiKey: theperfectheist2025," according to JFrog . What's not...
Microsoft Azure DevOps MCP Flaw Lets Hidden PR Comments Hijack AI Review Agents

Microsoft Azure DevOps MCP Flaw Lets Hidden PR Comments Hijack AI Review Agents

Jul 22, 2026 AI Security / DevSecOps
A single invisible comment in an Azure DevOps pull request can turn a reviewer's own AI coding agent against them, driving it into projects the attacker has no rights to reach and quietly leaking what it finds. The flaw is in Microsoft's official Azure DevOps MCP server , and it works because one of its tools returns pull request descriptions without a prompt-injection guardrail the company had already applied to others. Agentic Runtime Security firm Manifold Security detailed the confused-deputy bug this week. Microsoft ships the server so AI agents can read and operate Azure DevOps for a user, across pull requests, pipelines, wikis, and work items, all with the user's own permissions. That is the whole problem: content other people wrote can become instructions the agent acts on. Azure DevOps PR descriptions accept Markdown, which allows HTML comments. In the web UI, an HTML comment (<!-- ... -->) renders as nothing, so a reviewer scrolling the description s...
AWS Kiro Flaw Let a Poisoned Web Page Rewrite Its Config and Run Code

AWS Kiro Flaw Let a Poisoned Web Page Rewrite Its Config and Run Code

Jul 21, 2026 AI Security / Vulnerability
Hidden text on a web page was enough to make Kiro , AWS's agentic coding IDE, rewrite its own configuration file and run an attacker's code on a developer's machine, with no approval step able to stop it. Intezer, in research with Kodem Security, found that a request as ordinary as asking Kiro to summarize a page could end in remote code execution. AWS has patched the issue and says it is covered by CVE-2026-10591. Kiro's safety model rests on a human clicking "allow." The agent can run shell commands, fetch URLs, and edit files, and the design assumes a developer reviews anything risky before it happens. That approval step is the security boundary, and the flaw let an attacker slip past it without the developer ever being offered a choice. The weak point was the file that tells Kiro which external tools to load. Kiro reads its list of Model Context Protocol servers, and the exact command used to start each one, from ~/.kiro/settings/mcp.json. When th...
Google Launches Gemini 3.5 Flash Cyber AI to Find and Fix Software Vulnerabilities

Google Launches Gemini 3.5 Flash Cyber AI to Find and Fix Software Vulnerabilities

Jul 21, 2026 Software Security / Artificial Intelligence
Google's DeepMind on Tuesday announced the release of Gemini 3.5 Flash Cyber , a specialized artificial intelligence (AI) model built atop 3.5 Flash that's designed to discover, validate, and patch vulnerabilities quickly and efficiently. According to the tech giant, the model will be exclusively available to governments and trusted partners via CodeMender as part of a limited-access pilot program. CodeMender is an AI-powered agent for vulnerability discovery and patching that was unveiled by the company in October 2025. A Google DeepMind spokesperson told The Hacker News that there are plans to extend the model's capabilities to include red-teaming features and end-to-end enterprise defense. The lightweight model, per DeepMind, is both cost-efficient and highly capable alternative to large, costly cybersecurity-focused models. CodeMender can call upon 3.5 Flash Cyber "multiple times at high speed and low cost," allowing the AI agent to scan more code path...

Open-Source Android AI Agents Could Let Invisible Screen Text Run Code on Host PCs

Open-Source Android AI Agents Could Let Invisible Screen Text Run Code on Host PCs

Jul 21, 2026 Vulnerability / AI Security
An Android app that can draw over other windows and write to shared storage can slip instructions to the AI agent driving that phone, in text no human eye will ever see. Two more steps, and the same app is running commands on the PC driving the agent. Researchers demonstrated that chain, plus six other attacks, against five open-source mobile agent frameworks: AppAgent, AppAgentX, Mobile-Agent-v3, Open-AutoGLM, and MobA. Everyone fell to at least six of the seven. The paper went up on arXiv on July 1 and was revised on July 14. The authors are at Simon Fraser University, the Chinese University of Hong Kong, Shandong University, and the Xingtu Lab at Chinese security firm QAX. Nothing here has a CVE, and first author Zidong Zhang told The Hacker News the team has no evidence of the techniques being used outside a controlled setting. The Hacker News checked all five frameworks and found the screenshot paths, the shell call, and the broadcast fallback that the paper describes st...
