Claude Code and Gemini CLI Flaws Let a GitHub Issue Reach CI Workflow Secrets

Why it matters

Novee Security found that unprivileged GitHub issues could reach privileged coding-agent workflows: Gemini CLI and Claude Code paths led to CI-runner code execution, while a Codex path could alter the next agent run. The two assigned CVEs were patched; the Codex behavior was documented rather than assigned a product CVE, highlighting failures in the surrounding harness rather than the model alone.

My takeaway: Patch Gemini CLI to 0.39.1 or later, run-gemini-cli to 0.1.22 or later, and Claude Code to 2.1.163 or later. Audit every workflow reachable from public issues or pull requests, isolate and de-privilege runners, treat repository instructions as untrusted data, and require a trusted signal outside user-controlled text before privileged automation starts.

Pacing model development in an era of cyber-critical capabilities

OpenAI says preliminary evidence that Astra may meet its Critical cybersecurity threshold led it to pause frontier reinforcement-learning work for two weeks and keep its largest planned run on hold. New safeguards include stronger workload and network isolation, continuous boundary testing, token-level monitoring that escalates suspicious tool activity, and broader alignment checks for deception, reward hacking, and unauthorized access.

A blueprint for democratic governance of frontier AI

OpenAI proposes a three-part U.S. frontier-AI governance model: harmonize emerging state safety laws into a federal baseline, strengthen CAISI as an evaluation and standards institution, and coordinate a broader resilience program. Proposed controls include severe-risk evaluations, transparency reports, independent audits, safety-incident reporting, model-weight security, whistleblower protection, and periodic technical assessments.

OWASP Top 10 for Agentic Applications for 2026

OWASP's community guide organizes agentic-system risk into ten categories, including goal hijacking, tool misuse, identity and privilege abuse, memory poisoning, insecure inter-agent communication, cascading failures, and rogue-agent behavior. It provides a shared taxonomy and mitigation starting point rather than a certification checklist or evidence that a deployed system is secure.
