Policy bypass via uncorrelated parent evidence
Published Aug 31, 2026 · Updated Aug 31, 2026
Improper access control in @hulumi/policies before 1.3.2 allows remote attackers to bypass HULUMI-H1 bucket policy checks. The HULUMI-H1 validator accepts supplied SecureBucket parent evidence without correlating it to the expected component-resource relationship, so an unsafe bucket shape passes evaluation. Exploitation requires policy evaluation of attacker-controlled infrastructure evidence and can permit unsafe bucket configurations to pass as compliant.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
