CVE-2026-111259
Apache TomEE: Predictable HTTP session identifiers in embedded server
The embedded server generates HTTP session identifiers with a non-cryptographic random number generator by default. A remote attacker who observes a session identifier can predict the identifiers issued to other users and hijack their sessions, if the application relies on HTTP sessions for authentication. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
