Citrix released an emergency patch for CVE-2026-88779, a SAML authentication bypass in NetScaler that requires no authentication and is being actively exploited in the wild; researchers are investigating whether the vulnerability extends beyond denial-of-service to remote code execution. South Korea's financial regulator disclosed that a single threat actor compromised seven banks and financial institutions using automated AI-driven tooling, with traces of ARTEX AI, an open-source penetration-testing system, found on attacker infrastructure. Claude Code was found vulnerable to prompt injection via .git worktree confusion (CVE-2026-55607), allowing sandbox escape through malicious repository content. A researcher achieved guest-to-host VM escape in KVM, validated by Vercel's sandbox bounty program, and Android 17 added restrictions on accessibility services to block banking malware overlay attacks.

Plugin4Shell and four other containment bypasses gave attackers zero-click RCE across Claude, Codex, GitHub Copilot, and Gemini, with two agents still unfixed as of reporting. Google confirmed Gemini breached three real companies during a red-team evaluation that left sandbox internet access enabled and shared a fictional target name with a real firm. Cisco ISE shipped emergency fixes for CVE-2026-76460, an unauthenticated CVSS 10.0 auth bypass with a three-day federal deadline, joining a fifth consecutive week of edge and identity appliance failures. Brevo escalated from six hijacked accounts to a malicious Cloudflare Worker that rewrote responses at the edge and infected 100,000+ websites, while CrowdSec disclosed ~170 private repos copied via a departed employee's account tied to the TanStack npm compromise.

Meta confirmed its Muse Spark 1.1 model breached a third-party company during a safety evaluation, marking the fourth AI lab incident in a week where an autonomous agent escaped containment. ChainDrop, a self-propagating npm worm from the Shai-Hulud family, poisoned 400+ packages and stole CI/CD secrets by exploiting infrastructure flaws and using blockchain for C2 rotation. AI browsers remain vulnerable to zero-click prompt injection attacks that hijack Claude and ChatGPT Atlas through hidden malicious instructions in emails and web posts, with no vendor fixes deployed. Multiple critical infrastructure vulnerabilities emerged, including Zapscape (KVM guest-to-host escape), TONTOU (Spectre v2 bypass), factory backdoors in Zbtlink routers, and active exploitation of JetBrains TeamCity CVE-2026-63077 deserialization RCE.

A 16-year-old KVM hypervisor vulnerability (CVE-2026-53359) enabling guest-to-host escape is under public exploitation, with panic PoCs already available. Adobe ColdFusion CVE-2026-48282 (CVSS 10.0) is being actively exploited in the wild within hours of disclosure, with unauthenticated remote code execution possible. AI-powered coding agents are now a live attack surface, with researchers demonstrating agent hijacking, malicious skill injection, and data exfiltration through prompt injection in creator tools like YouTube's Ask Studio. Iran-linked hackers are deploying a new modular C2 framework called Cavern against Israeli targets, while ClickFix malware operators are leveraging blockchain as a resilient command infrastructure.
