Vulnerability Advisory : Contrast 1.21.0 before 1.25.0 Credential Leak via imagepuller Wildcard Registry Selection with HIGH Attack Complexity

Edgeless Systems Contrast from 1.21.0 before 1.25.0 contains a non-deterministic registry selection flaw in imagepuller that can prefer wildcard configuration entries over concrete domain matches. When a pull configuration lists both a concrete domain and its parent wildcard, registry credentials, CA bundles, or mirror settings intended for the wildcard may be applied to the concrete registry, leaking credentials or pull metadata.
