CVE-2026-86532
Apache TomEE: Username enumeration and timing side channel in JAAS login modules
CVSS Score
0.0
EPSS Score
0.0%
EPSS Percentile
0th
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.
