No CVSS score has been assigned to GHSA-59f3-7227-wmh4 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-59f3-7227-wmh4?

GHSA-59f3-7227-wmh4 affects the following packages: @hulumi/policies (npm). Ecosystems affected: npm.

How do I fix GHSA-59f3-7227-wmh4?

Update @hulumi/policies to 1.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-59f3-7227-wmh4 is resolved across your whole dependency graph.

How do I detect GHSA-59f3-7227-wmh4 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @hulumi/policies. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-59f3-7227-wmh4 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-59f3-7227-wmh4?

O3 pinpoints whether GHSA-59f3-7227-wmh4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-59f3-7227-wmh4 actively exploited in the wild?

No public exploit code has been indexed for GHSA-59f3-7227-wmh4 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-59f3-7227-wmh4 published, and has it been updated?

GHSA-59f3-7227-wmh4 was published on May 21, 2026 and was last updated on May 21, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Frequently Asked Questions

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.
