Severity: moderate Affected versions:
- Apache TomEE (org.apache.tomee:tomee-catalina) 8.0.7 before 10.0.0-M1 - Apache TomEE (org.apache.tomee:tomee-catalina) 10.0.0-M1 before 10.3.0 - Apache TomEE (org.apache.tomee:tomee-catalina) 11.0.0-M1 before 11.0.0-M2 Description: When resolving security roles of a realm-authenticated caller, the caller's user name is also treated as a role name in addition to the roles assigned by the realm. An authenticated attacker who can obtain an account whose user name equals a role name, for example through self-registration, is granted that role wherever authorization is evaluated through the Jakarta Authorization policy. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
