Vulnerability from github – Published: 2026-08-31 09:30 – Updated: 2026-08-31 09:30

Details

@hulumi/policies versions before 1.3.2 contain an evidence validation bypass vulnerability in Cloudflare and deployment-governance validators that allows attackers to suppress violations by submitting unrelated compliant evidence. Attackers can use evidence from different zones, hostnames, origins, or repositories to bypass security guardrails for unrelated resources in the same stack.
