The security researcher known as Chaotic Eclipse (aka INFINITE NIGHTMARE, MSNightmare, and Nightmare-Eclipse) has dropped a new zero-day dubbed FalconFlank , a privilege escalation flaw impacting Crowdstrike Falcon. "FalconFlank is a 0day privilege escalation that abuses the office malicious macros remediation in CrowdStrike Falcon Sensor," the researcher said in a GitHub README file, adding the cybersecurity company may already have detections for the flaw by now. "So if you want to test, you either have to add it to the exclusions or obfuscate the PoC and change the DLL load technique." The PoC, the researcher added, works in a fully updated Windows 11 25H2 machine or Windows Server 2025 with Crowdstrike Falcon. The Hacker News has contacted CrowdStrike for comment, and we will update the story if we hear back. The development comes days after Chaotic Eclipse released a PoC for another privilege escalation flaw impacting Kaspersky's endpoint securi...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added seven security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog after they landed in attackers' crosshairs. The vulnerabilities are as follows - CVE-2026-83548 (CVSS score: 10.0) - A server-side request forgery vulnerability in SonicWall SMA 1000 Appliances that could allow a remote unauthenticated attacker to gain unauthorized access to sensitive functionality and perform unauthorized operations.  CVE-2026-83549 (CVSS score: 7.8) - A post-authentication operating system command injection vulnerability in SonicWall SMA 1000 Appliances that could enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution. CVE-2026-9586 (CVSS score: 9.3) - An SQL injection vulnerability in Sangoma Switchvox that could allow an unauthenticated remote attacker to execute arbitrary SQL statements against the backend PostgreSQL...

Google on Wednesday announced Gemini 3.8 Flash Cyber, which it described as its most capable cybersecurity model, and has made it available to a set of trusted defenders via a new initiative called the Fairwind Program . "The Fairwind Program gives high-priority defenders (like governments, healthcare providers, and telecommunications services) early access to advanced models that help them build better defenses, before new threats arrive," Google said . "So defenders have an early advantage, to help them protect vital infrastructure – which in turn protects people who rely on those systems." The tech giant said it's currently working with over 650 partners globally, including CrowdStrike, Datadog, Menlo Security, Palo Alto Networks, and Snowflake. The program is available to a group of Google Cloud customers, government agencies, and cybersecurity partners. The release of Gemini 3.8 Flash Cyber comes a little over a month after Google unveiled Gemini 3....

Manifold Security has disclosed eight security flaws across seven command-line AI coding agents in which a repository's own Git configuration names a command that the agent runs on the developer's machine, four of them still unpatched at publication. The command executes as the user, outside the agent's sandbox and without an approval prompt, and exploitation requires the repository to arrive as files with its .git directory intact, which a shared archive, a shared drive, a sync folder, or a USB stick preserves, whereas an ordinary clone does not. Fixes have shipped for goose, Claude Code, and Cursor, while Hermes Agent, Qwen Code, Grok Build, and a second path in Claude Code were still executing repository-supplied commands when Manifold retested them on September 1. OpenAI published three CVEs of its own the same day covering the identical class in Codex, credited to three unrelated research groups. "The helper runs outside Codex's command sandbox and wi...

SonicWall has released security updates to address two security flaws impacting its Secure Mobile Access (SMA) 1000 series VPN appliances that have been exploited in zero-day attacks. The vulnerabilities , discovered internally by SonicWall's William Perry and Adam Babis, are listed below - CVE-2026-83548 (CVSS score: 10.0) -  A pre-authentication SSRF vulnerability in the Appliance Work Place interface that could allow a remote unauthenticated attacker to gain unauthorized access to sensitive functionality and perform unauthorized operations. CVE-2026-83549 (CVSS score: 7.8) - A post-authentication operating system command injection vulnerability in the Appliance Management Console (AMC) that could allow a remote authenticated attacker as administrator to execute arbitrary commands under specific conditions, leading to remote code execution. SonicWall said it has "investigated a case indicating the active exploitation of the vulnerabilities," suggesting th...
