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 stateful session bean passivation mechanism derives the on-disk file name from a client-supplied identifier without validating it. A remote attacker with access to the remote EJB service can cause session state to be read from or written to files outside the passivation directory. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
