Descriptions

Spring Framework running version 6.0.0 - 6.0.6 or 5.3.0 - 5.3.25 using "**" as a pattern in Spring Security configuration with the mvcRequestMatcher creates a mismatch in pattern matching between Spring Security and Spring MVC, and the potential for a security bypass.

A flaw was found in Spring Framework. In this vulnerability, a security bypass is possible due to the behavior of the wildcard pattern.

Red Hat support for Spring Boot provides an application platform that reduces the complexity of developing and operating applications for OpenShift as a containerized platform. This release of Red Hat support for Spring Boot 2.7.13 serves as a replacement for Red Hat support for Spring Boot 2.7.12, and includes security, bug fixes and enhancements. For more information, see the release notes linked in the References section. Issues addressed include bypass, code execution, denial of service, and deserialization vulnerabilities.
