Description

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier did not use a constant-time comparison function for validating connection secrets, which could potentially allow an attacker to use a timing attack to obtain this secret.

Solution(s)

  • jenkins-lts-upgrade-2_204_2
  • jenkins-upgrade-2_219
