CVE-2026-87758 PUBLISHED

Apache TomEE: Missing TLS hostname verification in ejbds client connections

Assigner: apache
Reserved: 09.09.2026 Published: 10.11.2026 Updated: 10.11.2026

The remote EJB client does not verify that the hostname of the server it connects to matches the server's TLS certificate. An attacker able to intercept network traffic between an EJB client and server can impersonate the server and read or modify the traffic, including credentials and invocation data. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
