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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

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.

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.

What is the EPSS score for GHSA-59f3-7227-wmh4?

GHSA-59f3-7227-wmh4 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 46th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-59f3-7227-wmh4?

GHSA-59f3-7227-wmh4 is classified as CWE-693 (CWE-693). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

No confirmed exploitation observed yet

CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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.
