@hulumi/policies: HULUMI-H1 SecureBucket parent spoof bypass
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
@hulumi/policiesnpmDescription
Impact: @hulumi/policies versions before 1.3.2 could accept spoofed SecureBucket parent evidence for HULUMI-H1, allowing policy evaluation to miss an unsafe bucket shape.
Patched in 1.3.2: the validator now correlates evidence to the expected component/resource relationship and includes regression coverage.
Remediation: upgrade @hulumi/policies to 1.3.2 or later.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update @hulumi/policies to 1.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g43v-9x7q-83pq is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-g43v-9x7q-83pq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-g43v-9x7q-83pq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-g43v-9x7q-83pq in your dependencies?
O3 detects GHSA-g43v-9x7q-83pq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
