Google GTIG's confirmation of the first AI-generated zero-day deployed in a live attack closes the loop on Monday's AI agent vulnerability wave, connecting the attack surface (vulnerable AI frameworks) to the attack tool (AI-generated exploits) in the same reporting week.
CVE-2026-0300 (CVSS 9.3) is an unauthenticated, root-level RCE in the PAN-OS User-ID Authentication Portal of PA-Series and VM-Series firewalls, under active exploitation by a likely China-aligned cluster Unit 42 tracks as CL-STA-1132. First hotfixes ship May 13. Anything with the Captive Portal exposed to untrusted networks needs immediate mitigation.
The rapid exploitation of CVE-2026-42208 in LiteLLM marks the first confirmed weaponization of the AI API proxy layer, while TeamPCP's new ransomware partnership turns out to be a wiper with no recovery path.
Three critical vulnerabilities under active exploitation target FortiClient EMS, Adobe Acrobat Reader, and nginx-ui, collectively exposing enterprise management planes and endpoints to unauthenticated remote code execution.
Three incidents this week reveal the same strategic pattern: attackers turning trusted defensive infrastructure into weapons. Microsoft Defender zero-days, the Trivy scanner compromise that breached the European Commission, and UNC6783's live-chat social engineering all exploit a cognitive constant: defenders don't question the tools they depend on.
