How widely exploitable is this vulnerability?

Exploitability depends on how Jervis is integrated into your Jenkins environment. If attackers can influence or inject ciphertext that Jervis will decrypt and can observe any difference in behavior or errors, the risk of practical exploitation increases significantly.

Does an attacker need authenticated access to Jenkins to exploit this?

Often some level of access is needed—such as the ability to edit job configurations, pipeline libraries, or parameters—but the exact requirement depends on your access controls and how encrypted values are stored or consumed. In weaker setups, lower-privileged users might still reach the vulnerable code paths.

What is the safest general fix pattern?

The most robust fix is to adopt an authenticated encryption scheme, such as AES-GCM or an encrypt-then-MAC construction, and ensure that decryption verifies integrity before acting on any plaintext. All legacy CBC-based code paths should be systematically retired or wrapped with strong integrity checks.
