Details
A vulnerability was found in Apache TomEE. It has been rated as critical. This issue affects an unknown functionality of the component Stateful Session Bean Passivation Mechanism. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
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.
It is possible to read the advisory at lists.apache.org. The identification of this vulnerability is CVE-2026-86811 since 09/08/2026. The exploitation is known to be easy.
