CVE-2026-82855

Policy bypass via unscoped stack evidence

Published Aug 31, 2026 · Updated Aug 31, 2026

Protection bypass in @hulumi/policies before 1.3.2 allows attackers to suppress policy violations with unrelated evidence. Cloudflare and deployment-governance validators accept stack-wide evidence without correlating its zone, hostname, origin, or repository to the protected resource. Reachability requires control of evidence in the evaluated stack, and the result is omitted guardrail findings for unrelated resources.
