Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jervis (Maven net.gleske:jervis) versions before 2.2 use AES/CBC/PKCS5Padding without authentication, which makes encrypted data open to padding oracle attacks and ciphertext manipulation. The source says the risk is low for internal use of the library, but could be critical for any consumer that calls these methods directly, and that Jervis's own use is unlikely to be affected because of an encrypted-key design and a SHA-256 checksum check. Upgrade to Jervis 2.2, which moves to AES/GCM/NoPadding. The source lists no workarounds.
