  • GHSA-g43v-9x7q-83pq@hulumi/policies: HULUMI-H1 SecureBucket parent spoof bypass2026-05-21ghsa · osvUS

    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.
