Description:

When using Apache Shiro before 1.11.0 together with Spring Boot 2.6+, a 
specially crafted HTTP request may cause an authentication bypass.

The authentication bypass occurs when Shiro and Spring Boot are using different 
pattern-matching techniques. Both Shiro and Spring Boot < 2.6 default to Ant 
style pattern matching.
Mitigation: Update to Apache Shiro 1.11.0, or set the following Spring Boot 
configuration value:  `spring.mvc.pathmatch.matching-strategy = 
ant_path_matcher`
