Last modified Jun 17, 2026

CVE-2023-22602 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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` . EPSS estimates a 1.55% chance of exploitation in the next 30 days.
