EPSS · scored 2026-10-28

@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.

  • GHSA-59f3-7227-wmh4@hulumi/policies: Stack-wide evidence bypassed Cloudflare and deployment-governance guardrails2026-05-21ghsa · osvUS

    Impact: @hulumi/policies versions before 1.3.2 used stack-wide evidence shortcuts in several Cloudflare and deployment-governance validators. Unrelated compliant-looking evidence could suppress violations for different zones, hostnames, origins, or repositories in the same stack. Patched in 1.3.2: validators now correlate evidence to the specific protected resource and include regression coverage for unrelated-evidence bypasses. Remediation: upgrade @hulumi/policies to 1.3.2 or later.
