Summary
@hulumi/policies: HULUMI-H1 SecureBucket parent spoof bypass
Details

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.

Severity
8.7 (High)
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N
