Red Hat Lightwell has released org.springframework:spring 5.3.18.rhlw-00010 with a backported security fix.
CVE-2023-20860: 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.
This patched artifact is a drop-in replacement for org.springframework:spring 5.3.18 from Maven Central.
