Overview
Affected versions of this package are vulnerable to Replay Attack in the nonceVerifier process. An attacker can gain unauthorized access by replaying previously captured Digest authentication responses. This is only exploitable if the default configuration is used without supplying a custom nonceVerifier.
Workaround
This vulnerability can be mitigated by explicitly providing a nonceVerifier that tracks issued nonces, enforces a time-to-live (TTL), and rejects reuse.
