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 pad SHA-256 hex strings to 32 characters instead of 64, so hashes with leading zero bytes come out with inconsistent lengths. The source describes the impact as comparison failures and possible security issues in hash-based comparisons, and says the risk is high only if consumers call these methods directly. Upgrade to Jervis 2.2. The source lists no other workaround beyond using a different hash function.
