Monitoring evasion via incomplete selector event matching
Published Aug 31, 2026 · Updated Aug 31, 2026
Insufficient logging in @hulumi/baseline before 1.3.2 allows attackers to evade CloudTrail selector-tampering alerts. SecurityDetectionFoundation leaves some selector-change events outside its CloudTrail alarm filters, so those changes lack complete monitoring coverage. Attackers must already be able to modify CloudTrail event selectors; the flaw reduces audit visibility rather than granting AWS permissions.

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.
