What happened
A weekly security recap covering a CVSS 10.0 Cisco ISE auth bypass (CVE-2026-76460) under active exploitation, AI agent remote code execution vulnerabilities, surging ClickFix social-engineering attacks that trick developers into running malicious code, and a case where Hacktron used Anthropic's Claude Opus 5 to chain two critical vulnerabilities (including an SSO misconfiguration) against OpenAI.
Why it matters
If you build or deploy AI agents, the AI agent RCE finding means you should audit agent tool-calling and code-execution surfaces before shipping. ClickFix attacks targeting developers through fake error-fix copy-paste prompts mean your team needs a policy against blindly running clipboard content from web pages. The Claude-vs-OpenAI chaining demonstrates that LLMs can now automate multi-step exploit discovery, raising the bar on input validation for any SaaS handling SSO.
Discussion angle
How ClickFix attacks exploit developer habits (copy-pasting 'fixes' from popups) and what practical guardrails—clipboard monitoring, browser policies, or sandboxing—your team can put in place this week.
