AI Vendors Avoid Fixing Critical Security Flaws

by Let’s Do Science

AI vendors are deflecting responsibility for security flaws, labeling exploitable behaviors as “working as intended” and choosing documentation changes or token bounties over systemic fixes. Researchers demonstrated hijacks against Claude Code Security Review, Gemini CLI Action, and GitHub Copilot that can exfiltrate API keys and tokens. Vendors paid small rewards, $100, $1,337, $500, but did not assign CVEs or publish full advisories.

Technical details

The incidents split into two classes. First, agent integrations with CI/CD (GitHub Actions) allow malicious inputs or crafted workflows to trigger credential leaks; remediation requires changes to how agents handle action context, secrets, and runner permissions. Second, a protocol-level issue in MCP stdio was classified as “expected behavior,” yet researchers say a root fix would have reduced exposure across packages with more than 150 million downloads and protected up to 200,000 servers. Vendors cited design tradeoffs rather than issuing patches, leaving high- and critical-severity CVEs at the open-source tooling layer without upstream consolidation.

Context and significance

This is not isolated tech drama; it reflects a broader maturity gap in how AI product teams handle security. AI systems operate as runtime components in developer pipelines and infrastructure, so deferring fixes amplifies supply-chain risk. The behavior also undercuts responsible disclosure norms: small bounties and documentation edits do not compensate for absent CVE triage, coordinated advisories, or mitigations that reduce attack surface for downstream integrators.

What to watch

Security teams should treat vendor statements of “expected behavior” as a red flag, perform independent threat modeling for agent integrations, and push vendors for CVE assignments and coordinated disclosures. Incident-driven fixes will remain partial unless the industry adopts stronger remediation standards and shared protocols for agent safety and secret handling.
