Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring Security's spring-security-config package, versions 5.6.0 to before 5.6.12, 5.7.0 to before 5.7.10, 5.8.0 to before 5.8.5, 6.0.0 to before 6.0.5, and 6.1.0 to before 6.1.2, is affected. The source describes a pattern-matching mismatch between Spring Security and Spring WebFlux when "**" is used as a pattern in WebFlux security configuration, which can lead to a security bypass; it gives few details on the exact conditions. Upgrade to 5.6.12, 5.7.10, 5.8.5, 6.0.5, 6.1.2 or later.

Written 8 Nov 2026.
