CVE-2026-86532
Published:November 10, 2026
Updated:November 14, 2026
The bundled JAAS login modules leak whether a username exists and compare credentials in a non-constant-time manner. A remote unauthenticated attacker can enumerate valid accounts and may infer credential material through timing analysis. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
