AI-suggested

Users should upgrade affected Apache TomEE installations to version 10.3.0 or 11.0.0-M2, where the authorization bypass issue is fixed. No other mitigation or temporary workaround is indicated in the advisory.

Description

Apache TomEE versions from 10.1.1 up to but not including 10.3.0, and from 11.0.0-M1 up to but not including 11.0.0-M2, running on JDK 21 or later, skip EJB method authorization checks. This allows callers to invoke EJB methods without enforcement of configured access restrictions. The issue is fixed in versions 10.3.0 and 11.0.0-M2.
