AI-suggested

Users should upgrade Apache TomEE to version 10.3.0 or 11.0.0-M2, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated in the advisory.

Description

Apache TomEE versions prior to 10.3.0 and 11.0.0-M2 have a vulnerability in MicroProfile JWT authentication where the security state for a request is not always cleared from the processing thread if the request does not complete normally. This can allow a remote attacker with a valid token to cause unrelated requests on the same thread to execute with elevated run-as identity privileges. Upgrading to versions 10.3.0 or 11.0.0-M2 mitigates this issue.
