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. 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 paths and find vulnerabilities. The release of 3.5 Flash Cyber comes alongside Gemini 3.6 Flash and 3.5 Flash-Lite , which are optimized for improved coding, knowledge work, and multi...

A third SharePoint Server flaw patched by Microsoft as part of its Patch Tuesday update for July 2026 has come under active exploitation, per watchTowr . The vulnerability in question is CVE-2026-50522 (CVSS score: 9.8), a critical deserialization of untrusted data in Microsoft Office SharePoint that could allow an unauthorized attacker to execute code over a network. Microsoft credited DEVCORE researcher "splitline" with discovering and reporting the flaw. "In a network-based attack, an attacker authenticated as at least a Site Owner, could write arbitrary code to inject and execute code remotely on the SharePoint Server," Redmond said in an advisory released last week. "The attack vector is Network (AV:N) because this vulnerability is remotely exploitable and can be exploited from the internet. The attack complexity is Low (AC:L) because an attacker does not require significant prior knowledge of the system and can achieve repeatable success with the ...

Threat actors have been observed exploiting a now-patched high-severity Palo Alto Networks PAN-OS vulnerability as an entry point to deploy Qilin (aka Agenda) ransomware on victim environments. Arctic Wolf Labs said it investigated multiple intrusions in June 2026 that began with the exploitation of CVE-2026-0257 (CVSS score: 7.8), an authentication bypass flaw affecting the portal and gateway components of PAN-OS software. Successful exploitation of the flaw allows unauthenticated remote attackers to sidestep authentication and establish VPN sessions without valid credentials when authentication override cookies are enabled with specific certificate configurations. "Post-exploitation tradecraft varied across intrusions, from rapid encryption-only operations to full double-extortion, possibly suggesting multiple affiliates operating under the Qilin ransomware-as-a-service (RaaS) umbrella," the cybersecurity company said .

Zimbra has rolled out fixes to address multiple critical security issues, including a command injection flaw in the Simple Network Management Protocol (SNMP) monitoring component. As many as nine security vulnerabilities have been patched in Zimbra 10.1.20 . Topping the list is a command injection vulnerability in the SNMP monitoring component when SNMP notifications are enabled. Also patched are four cross-site scripting (XSS) flaws in the Classic Web Client - A stored cross-site scripting (XSS) vulnerability that could allow malicious attachment filenames to execute script under specific conditions. An XSS vulnerability where crafted fields could execute a malicious script under specific conditions. An XSS vulnerability where a crafted field could execute a malicious script when rendered. An XSS vulnerability where crafted attachments could execute a malicious script when rendered. Separately, fixes have been released for a mail forwarding restriction bypass (CV...

Threat actors are now exploiting a recently disclosed critical security flaw impacting ServiceNow AI Platform, according to Defused Cyber . In a post shared on X, the threat intelligence firm said it's observing in-the-wild exploitation of CVE-2026-6875 (CVSS score: 9.5), a sandbox escape vulnerability that could allow an unauthenticated user to run arbitrary code. Patches for the flaw were released by ServiceNow throughout June in the following versions - Brazil EA and Brazil GA Australia Patch 2 Zurich Patch 7b and Zurich Patch 9 Yokohama Patch 12 Hot Fix 1b and Yokohama Patch 13 Searchlight Cyber, which disclosed additional technical specifics, said it reported the issue on April 1, 2026, adding it allows a complete compromise of the ServiceNow instance as well as all connected proxy servers. Besides rolling out a fix, ServiceNow is "enhancing instance security by severely restricting the type of code that can run in sandbox contexts," securit...

The industry spent the initial months after Anthropic's April 7 Mythos reveal focused on volume . How many new CVEs would Mythos add to an already overloaded pipeline? How quickly would the flood of AI-driven discovery overwhelm triage capabilities? How long would it take adversaries to weaponize Mythos findings at scale? Those questions were and remain valid. Yet they all stop short of addressing the single metric that determines whether any of those vulnerabilities actually lead to a breach: the exposure window. The exposure window - the gap between the moment a vulnerability becomes exploitable and the moment your team fixes it - is the time an attacker has to do actual damage. That window is currently open far too wide. In 2025, the average eCrime breakout time dropped to 29 minutes . Even PCI DSS - the strictest compliance framework in the industry - allows 30 days to remediate a critical vulnerability. That's a 1,000-to-1 gap between how fast attackers move and how f...

A previously undocumented threat actor has been attributed to the exploitation of recently disclosed SonicWall Secure Mobile Access (SMA) 1000 series VPN appliances as zero-days prior their public disclosure since June 22, 2026. Cybersecurity company Volexity is tracking the activity under the moniker UTA0533 . The discovery was made following an incident response investigation earlier this month. The impacted organization has not been identified. "This threat actor was observed using multiple zero-day exploits, malware designed specifically for SonicWall SMA VPN appliances, as well as other attacker tradecraft," security researchers Sean Koessel and Steven Adair said in an analysis. The vulnerabilities in question are CVE-2026-15409 (CVSS score: 10.0) and CVE-2026-15410 (CVSS score: 7.2), both of which could be chained to facilitate arbitrary command execution and take over susceptible devices. Patches for both the vulnerabilities were released by SonicWall this wee...

ACR Stealer , an infostealer in circulation since 2024, is walking out of enterprise networks with saved browser passwords, live session tokens, PDFs, Microsoft 365 documents, and files from synced OneDrive and SharePoint folders. It gets in because someone pasted a command into a Run box and pressed Enter. Microsoft laid out two of the delivery chains on Thursday. Its Defender Experts team, the company's managed detection arm, had watched ACR Stealer activity climb across customer environments from late April to mid-June, and says the campaigns are "successfully using ClickFix lures to steal browser credentials, authentication tokens, and sensitive documents." Both chains open with the same prompt, then split: one leaves traces on disk, the other runs almost entirely in memory. Microsoft's remediation guidance tells victims to revoke tokens, not just rotate passwords. A payload in the pixels The prompt likely arrives through malvertising or SEO-manipulated...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a newly patched security flaw impacting Microsoft SharePoint Server to its Known Exploited Vulnerabilities ( KEV ) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by July 19, 2026. The vulnerability in question is CVE-2026-58644 (CVSS score: 9.8), a critical deserialization of untrusted data vulnerability that allows an unauthorized attacker to execute arbitrary code. "In a network-based attack, an attacker authenticated as at least a Site Owner, could write arbitrary code to inject and execute code remotely on the SharePoint Server," Microsoft said in an advisory released earlier this week. Redmond noted that the vulnerability is remotely exploitable over the internet, warning that the attack complexity is low for two reasons - An attacker does not require significant prior knowledge of the system An attacker can achieve repeatable su...

n8n , the workflow automation platform, handed out the wrong accounts at login. On Enterprise instances configured to trust more than one external token issuer, it matched an incoming JWT to a local user on the  sub  claim alone and ignored  iss . A valid token from issuer A carrying a  sub  that belongs to someone under issuer B logged you in as them. Their password never came into it. n8n shipped the fix on June 24. The flaw is tracked as  CVE-2026-59208 . The CVE record did not go public until July 9. n8n  credits the report  to the GitHub account bearsyankees , whose profile lists Strix, which makes an AI penetration testing agent. Strix  says  it pointed out that the agent at the token-exchange flow and found the identity-binding bug there. Two issuers, one account Token exchange is n8n's Enterprise route for  OEM partners who embed the product , an  RFC 8693 implementation  that spares their users a second...

Zoom has released security updates for a critical security flaw impacting Zoom Workplace for Windows that could facilitate account takeover. The vulnerability, tracked as CVE-2026-53412 (CVSS score: 9.8), affects Zoom Workplace for Windows before version 7.0.0 and Zoom Workplace VDI Client for Windows before version 7.0.10, 6.6.15, and 6.5.18 in their respective branches. "Improper Input Validation in Zoom Desktop Client for Windows and Zoom VDI Client for Windows may allow an unauthenticated user to conduct an account takeover via network access," Zoom said in an advisory released this week. The latest security fixes also address three high-severity flaws - CVE-2026-53411 (CVSS score: 7.8) - An improper input validation vulnerability in the Zoom Workplace VDI Plugin for Windows before version 6.6.14 that may allow an authenticated user to conduct an escalation of privilege via local access. CVE-2026-53410 (CVSS score: 7.0) - A time-of-check to time-of-use ...

Mozilla has released updates to address two critical flaws in Firefox for which it warned that exploit code has been published. The vulnerabilities are listed below - CVE-2026-15718 , an invalid pointer in the JavaScript: WebAssembly component CVE-2026-15719 , a site isolation in the DOM: Navigation component "We are aware that exploit code for this is public, however we are not aware of any attacks in the wild abusing this flaw," Mozilla said in an advisory. Both vulnerabilities have been addressed in Firefox version 152.0.6. The release comes as Google shipped fixes for 15 security flaws, including two critical use-after-free bugs in Ozone ( CVE-2026-15764 and CVE-2026-15765 ), a cross-platform abstraction layer that allows the browser to interact natively with various display servers and windowing systems. It supports Linux, ChromeOS, and Fuchsia. "Use after free in Ozone in Google Chrome on Linux prior to 150.0.7871.125 allowed a remote attacker...

For years, routing traffic through cloud proxies was good enough. Then work moved to the browser, AI entered the workflow, and the inspection model stopped keeping up. Enterprise workflows now live across SaaS applications, browsers, and an expanding ecosystem of generative AI tools, unsanctioned browser extensions, and autonomous agents. Employees routinely paste intellectual property into public LLMs for code optimization, while automated agents query internal documentation and move data across systems at machine speed. The challenge is not that SASE failed, but that data interactions have shifted to the presentation layer, an area network-centric architectures were never designed to see. This structural paradigm shift is explored in detail within The Guide to Modern SASE Architecture . Why Traditional Enforcement Struggles Traditional SASE relies on backhauling traffic to cloud proxies for decryption, inspection, and policy enforcement. However, modern internet protocols, spe...

Security researcher Chaotic Eclipse (aka Nightmare-Eclipse ) has released a new proof-of-concept (PoC) exploit called LegacyHive. It has been described as a Windows User Profile Service arbitrary hive load elevation of privileges vulnerability. The Windows User Profile Service, also referred to as ProfSvc, is a core system component that manages user accounts and environments. "The PoC requires another standard user credential and a third username (which can be an administrator account)," Chaotic Eclipse said . "If the PoC is successful, it will end up mounting the target user hive in the current user classes root." The researcher said the exploit was stripped down to prevent public exploitation, adding the original exploit did not require additional user credentials and was not limited to the "usrclass.dat" hive. "Any hive could be loaded using this vulnerability, but you would need some brain cells to make the PoC do it," the researc...

SonicWall has warned of active exploitation of two zero-day vulnerabilities impacting Secure Mobile Access (SMA) 1000 series appliances, one of which could be exploited to achieve arbitrary command execution. The vulnerabilities are listed below - CVE-2026-15409 (CVSS score: 10.0) - A Server-side request forgery (SSRF) vulnerability that a remote unauthenticated attacker could exploit to potentially cause the appliance to make requests to an unintended location. CVE-2026-15410 (CVSS score: 7.2) - A post-authentication code injection vulnerability rooted in the Appliance Management Console (AMC) that a remote authenticated attacker could exploit to execute arbitrary operating system commands as administrator under certain conditions. SonicWall said it has "investigated multiple cases indicating the active exploitation of the vulnerabilities," urging customers to apply the fixes as soon as possible. The patches are available in the following versions - 1...

Microsoft shipped its largest Patch Tuesday on record today, and two of the fixes close holes that attackers are already exploiting. The release covers 622 of Microsoft's own CVEs by its  Security Update Guide  count, more than triple  June's previous high of around 200 . Those two live bugs are the ones to grab first. Microsoft credits incident responders for both. Both are elevation-of-privilege flaws in identity and collaboration infrastructure: CVE-2026-56164 in on-premises SharePoint Server and CVE-2026-56155 in Active Directory Federation Services. Neither is one of the splashy remote code execution criticals. They are privilege bugs in two systems that matter more than their scores suggest: the company document store, and the box that signs its logins. The two zero-days to patch first CVE-2026-56164 , a SharePoint Server flaw Microsoft says is being exploited in attacks, lets an unauthenticated attacker escalate privileges over the ne...

SAP has rolled out updates to address multiple vulnerabilities as part of its July 2026 security updates, including a critical flaw in SAP NetWeaver Application Server ABAP. The vulnerability in question is CVE-2026-44747 (CVSS score: 9.9), an out-of-bounds write flaw that allows an authenticated attacker to leverage logical errors in memory management to cause a memory corruption that could lead to unauthorized data access, modification, or system unavailability. "As a temporary workaround the note proposes to disable all ICF nodes with a specific property in transaction SICF," SAP security firm Onapsis said . "Since the workaround will disable opening transactions in SAP GUI for HTML, it is not an option for all customers and it is strongly recommended to install the patching ABAP Kernel version." Also addressed by SAP are two other critical vulnerabilities - CVE-2026-27690 (CVSS score: 9.1) - An HTTP request/response smuggling flaw in SAP Approuter...

Cybersecurity researchers have disclosed details of two access control-related flaws impacting the RabbitMQ message broker service that could allow attackers to leak OAuth client secrets, expose enterprise messaging infrastructure to takeover risks, and bypass tenant boundaries. Miggo's security team, which discovered and reported the flaws, said one "leaks the broker's confidential OAuth secret to an unauthenticated attacker in a single request, a direct path to full broker takeover in the configurations that use that secret." The second vulnerability allows any logged-in user to silently read other tenants' data. Both shortcomings are said to have been present in the codebase since early 2024, impacting RabbitMQ release lines from 3.13.0 and later. They have been addressed in versions 4.3.0, 4.2.6, 4.1.11, 4.0.20, and 3.13.15. There is no evidence of active exploitation of either of the vulnerabilities prior to the public disclosure. A brief description ...

AI security agents are starting to influence real security decisions. They summarize findings, prioritize remediation, recommend next steps, and help teams move faster. But most still rely on fragmented risk signals: scanner output, severity scores, threat intelligence, configuration findings, and exposure data. That fragmentation matters because attackers do not move through environments one tool category at a time. They chain exposures across identities, networks, cloud assets, applications, and security controls. If the AI workflow only sees isolated findings, it cannot understand whether those findings create a real attack path. As AI-powered attackers accelerate exploitation, security teams need more than faster AI-assisted workflows. They need workflows grounded in evidence that can prove which risks are exploitable. These systems can correlate information and identify patterns, but without validation, they cannot answer the question security teams ultimately care about: C...

xAI's Grok Build coding CLI was uploading entire Git repositories, full commit history and all, to a Google Cloud Storage bucket run by xAI, not just the files a coding task needed. A researcher publishing as cereblab , testing version 0.2.93 , captured one of those uploads, cloned the git bundle out of the intercepted request, and pulled back a file the agent had been told in plain terms not to open. The upload rode a separate channel from the model itself, and the byte split is hard to argue with. On a 12 GB repo of files the model never read, model-turn traffic to /v1/responses came to about 192 KB while the storage channel to /v1/storage moved 5.10 GiB, a roughly 27,800x gap between what the model needed and what left the machine. That storage upload ran as 73 chunks of about 75 MB, every one returning HTTP 200, and across the researcher's size sweep the volume tracked total repo size. The destination bucket, grok-code-session-traces , is named in the binary and ...
