Adobe has released security updates to address a maximum-severity security flaw in Campaign Classic (ACC), its enterprise-focused marketing automation platform, that could result in arbitrary code execution. The vulnerability, tracked as CVE-2026-48449 , carries a severity score of 10.0 on the CVSS scoring system. It has been described as a case of incorrect authorization that could result in arbitrary code execution in the context of the current user without requiring any user interaction. The update also resolves another high-severity flaw ( CVE-2026-48448 , CVSS score: 8.6) stemming from SQL injection that could pave the way for arbitrary file reads. "This update addresses critical vulnerabilities that could result in arbitrary code execution and arbitrary file system read," Adobe said in an advisory. The company noted that it's not aware of any of the flaws being exploited in the wild. Both shortcomings have been addressed in ACC v7: 7.4.3 build 9398 for W...

Google on Thursday announced that it fixed a whopping 1,072 security bugs in Chrome versions 149 and 150, surpassing the total number of flaws the company fixed across the prior 23 milestones combined. Both versions were released last month. In its latest patch for Chrome 151, released Wednesday, the tech giant resolved 370 flaws , out of which 349 were reported by Google itself. Seven of the vulnerabilities have been marked critical in severity. The development comes amid an exponential surge in vulnerability discovery, mainly fueled by the advent of large language models (LLMs) that have accelerated the process, leading to an unprecedented spike in new bug reports, so much so that issues are being flagged at a faster rate than companies can fix them. According to statistics shared by the U.S. National Vulnerabilities Database (NVD), 46,872 flaws have been recorded so far in 2026, nearing the 49,920 vulnerabilities reported for the entirety of 2025.

Palo Alto Networks' Unit 42 says a Chinese-speaking threat actor used DeepSeek through the open-source Hermes Agent framework to launch attacks autonomously. After an initial Telegram instruction, the agent found internet-facing systems and selected public exploits. The researchers recovered no further operator input in the session. The operator, tracked through the aliases knaithe and KnYuan , launched exploitation attempts against more than 460 targets using autonomous and conventional workflows. Unit 42 described seven exploit tracks. They span eight Common Vulnerabilities and Exposures (CVE) identifiers because the n8n chain combines two vulnerabilities. The DeepSeek-led attacks against Langflow and n8n failed because the exposed systems did not meet the exploits' configuration requirements. In separate manual operations, Unit 42 reported data exfiltration from three organizations through the NetScaler memory-overread flaw CVE-2026-3055 and command execution on 11...

Anthropic on Thursday became the latest artificial intelligence (AI) company to reveal that three of its models, including Claude Opus 4.7, Mythos 5, and an unnamed research model, had breached three unnamed organizations during cybersecurity testing without its knowledge. The AI firm said the earliest incidents date back to April 2026, adding it made the discoveries after launching a "large-scale retrospective review" in response to a recent disclosure from OpenAI that a combination of its models escaped the sandboxed environment by exploiting a previously unreported zero-day in Artifactory to obtain internet access and break into Hugging Face's production systems with an end goal to cheat on an evaluation. "After reviewing 141,006 evaluation runs where Claude could have obtained internet access, we identified three incidents in which a model accessed the internet from within or while interacting with the evaluation environment of Irregular, one of our third-...

Amazon has tied the September 2025 hijack of the npm packages debug and chalk to North Korea. For ten months, the incident sat in the public record as crypto theft: a maintainer phished through a lookalike npm domain and a wallet-draining script pushed into at least 18 packages carrying more than 2 billion weekly downloads between them. The original Aikido and Wiz reports did not attribute the incident to North Korea. In research published July 29, Amazon Threat Intelligence assesses with medium confidence that the group behind the March 2026 axios compromise was behind it. The same group planted a trojanized file in a small package called typo-crypto in March 2025, according to Amazon, a full year before it reached axios. Analysts found it while chasing a domain registered in 2025 that surfaced during the axios investigation. Downloads were low, but the tradecraft "aligns with what we later observed in attacks on more popular packages," Amazon wrote, and the compa...

Ruby on Rails has released fixes for a critical Active Storage vulnerability that could let unauthenticated attackers read arbitrary files from application servers through crafted image uploads. Tracked as CVE-2026-66066 (CVSS score: 9.5), the flaw can expose the Rails process environment and secrets such as secret_key_base , the Rails master key, database passwords, cloud storage credentials, and API tokens. Those secrets may enable remote code execution (RCE) or lateral movement into connected systems. Affected applications use libvips for Active Storage image processing and accept image uploads from untrusted users. Rails selects Vips under load_defaults 7.0 , and later defaults retain it. Ethiack and GMO Flatt Security list the affected ranges as Rails 7.0.0 through 7.2.3.1, Rails 8.0.0 through 8.0.5, and Rails 8.1.0 through 8.1.3. Rails 6.0.0 through 6.1.7.10 releases are affected only when Active Storage is configured to use Vips, which was not the default processor in Ra...

Cybersecurity researchers have flagged a maximum-severity security flaw in Ruflo , an open-source agent meta-harness for Anthropic Claude Code and OpenAI Codex, that could result in unauthenticated remote code execution. The vulnerability, tracked as CVE-2026-59726 (CVSS score: 10.0), impacts all versions of the project before version 3.16.3. It has been codenamed RufRoot by Noma Security's research team, Noma Labs. Originally launched as Claude Flow, Ruflo is an AI multi-agent orchestration platform and harness that allows users to deploy multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. The project has more than 66,500 stars on GitHub. The crux of the vulnerability is that Ruflo exposed 233 tools, including shell command execution, database operations, agent management, and memory storage, through an unauthenticated Model Context Protocol (MCP) bridge that's open to the network by default. Specifically, the "docker-comp...

OpenAI on Tuesday revealed the rogue artificial intelligence (AI) agent that escaped its sealed evaluation environment and broke into Hugging Face's production environment also hacked multiple third-party accounts and services as part of the attack. The latest disclosure shows that the security incident, which stemmed from an internal security test, was more extensive in scope than previously thought. The AI company said its ongoing review of the incident revealed a "small number of cases" where the models, including GPT-5.6 Sol and an "even more capable pre-release model," identified and used exposed credentials at the account-level on other publicly-available services. "This includes four accounts on four services as part of the Hugging Face incident (and a few accounts accessed as part of other evaluations)," it said. "One of these four accounts was used as an outbound relay and staging path, and another account was used for data st...

Gitea, the self-hosted Git platform, has patched a critical remote code execution vulnerability. A user with ordinary repository write access can turn attacker-controlled patch content into a live Git hook and run shell commands as the Gitea service account. Tracked as CVE-2026-60004 (CVSS score: 9.8), the flaw affects Gitea versions 1.17 and later before 1.27.1 and is fixed in 1.27.1. The vulnerable API call requires authentication and repository write permission. But Gitea enables registration by default, so an outside visitor can create a normal account and repository on an unchanged installation, then exploit the bug without pre-existing credentials. Upgrading to 1.27.1 is the fix. Gitea said on July 27 that Gitea Cloud instances would be upgraded automatically. Gitea's July 28 advisory does not say the flaw has been exploited in the wild, but it includes public proof-of-concept (PoC) code. Disabling open registration can remove the public account-creation path while th...

JFrog has confirmed that OpenAI models exploited a zero-day in self-hosted Artifactory while trying to reach the open internet from a sealed evaluation environment. Artifactory is JFrog's software repository manager. OpenAI says the models then escalated privileges and moved laterally until they reached an internet-connected node. JFrog says it has since developed and released fixes for cloud and self-hosted customers. The Artifactory exploit occurred inside OpenAI's environment. OpenAI says a separate attack path later reached Hugging Face's systems. JFrog says its cloud customers are already protected. Self-hosted users should review the Artifactory release notes and move to the remediating build for their maintained branch. Several Artifactory CVE records were published on July 27 with affected-version ranges and fixed-version thresholds, but neither JFrog nor OpenAI has said whether any of those records correspond to the vulnerabilities used during the evaluati...

JetBrains is urging customers of on-premise versions of TeamCity to update to the latest version following the discovery of a critical security issue that could result in arbitrary code execution. The vulnerability, assigned CVE-2026-63077 (CVSS score: 9.8), affects all TeamCity On-Premises versions. It has been addressed in versions 2025.11.7 and 2026.1.3. TeamCity Cloud instances have already been updated. JetBrains has credited Antoni Tremblay with discovering and reporting the flaw on July 10, 2026. "If exploited, this flaw may enable an unauthenticated attacker with HTTP(S) access to a TeamCity server to bypass authentication checks and execute arbitrary operating system commands with the privileges of the TeamCity server process," JetBrains said. The flaw allows unauthenticated remote code execution via the agent polling protocol to sidestep authentication checks and achieve command execution. Depending on the privileges granted to the TeamCity server process, ...

Microsoft has launched its first cybersecurity-specific model inside MDASH , its multi-model vulnerability identification and remediation harness. The company says MDASH, using MAI-Cyber-1-Flash and GPT-5.4, scored 95.95% on CyberGym. It also claims the configuration costs 50% less than its current best MDASH combination of GPT-5.4, GPT-5.4 mini, and GPT-5.3 Codex. Access is limited to approved MDASH customers through an Azure AI Foundry private preview. MAI-Cyber-1-Flash is designed to handle up to 90% of MDASH tasks, with GPT-5.4 reserved for the hardest 10%. It is available only inside MDASH, not as a standalone public model or general-purpose application programming interface. The headline score belongs to MDASH running MAI-Cyber-1-Flash alongside GPT-5.4, not to the new model by itself. CyberGym Level 1 is a known-vulnerability reproduction test. It gives an agent a vulnerability description and the corresponding unpatched source code, then checks whether it can produce a ...

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 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 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 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...

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...

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. ...

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...

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...
