Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Maven package net.gleske:jervis is affected in versions before 2.2. It uses a non-cryptographic random number generator to add random delays meant to mitigate timing attacks, so an attacker who can predict those delays may still be able to carry out timing attacks. Upgrade to Jervis 2.2, which switches to a cryptographically secure random generator.
