Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

The embedded OpenEJB HTTP server does not isolate HTTP sessions between web applications. A remote attacker can use a session established in one web application in another one, which then trusts session state set by the first application. Only deployments hosting several web applications on the embedded HTTP server are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
