Jenkins Open Redirect via Relative Path Segments in Post-Login Redirect URL

  • Disclosed: 10.06.2026
  • Updated: 11.10.2026 13:20

Jenkins 2.567 and earlier, LTS 2.555.2 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins when it contains relative path segments (./ or ../), allowing attackers to perform phishing attacks.
