Research from Veracode and CSET (February 2026) confirms that AI-assisted coding tools are generating insecure code patterns — including CWE-20, CWE-284, CWE-829, and CWE-1357 — at a velocity that exceeds current gate-based security review capacity, with blast radius compounded by simultaneous propagation across all projects sharing the same agent and prompt patterns. This is a structural risk item without a CVE, requiring security controls to move inside the development agent layer rather than remaining as downstream checkpoints. Organizations should inventory all AI coding tools in use, enforce SAST and SCA at PR creation, apply least-privilege identities to CI/CD pipeline agents, and track OpenSSF and CISA guidance on agentic system governance.
