Medium (6.5) in apache shiro. EPSS 1.2% chance of exploitation in the next 30 days. Fixed in org.apache.shiro:shiro-core 1.13.0, 2.0.0-alpha4.
Apache Shiro before 1.13.0 or 2.0.0-alpha-4, may be susceptible to a path traversal attack that results in an authentication bypass when used together with path rewriting
Mitigation: Update to Apache Shiro 1.13.0+ or 2.0.0-alpha-4+, or ensure `blockSemicolon` is enabled (this is the default).
