Description

Secrets Manager secret resource policies should not grant access to wildcard principals (Principal: "*") without scoping conditions. An unconditional wildcard principal allows any AWS account or unauthenticated user to access the resource, creating a significant security risk. Wildcard principals scoped by policy conditions (such as aws:SourceAccount, aws:SourceArn, or aws:PrincipalOrgID) are not flagged, because the condition restricts effective access.

Remediation

Update the resource policy to specify explicit principals. Alternatively, add scoping conditions that restrict access. For guidance, refer to Resource-based policies for Secrets Manager.
