Machine-written summary

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

Spring Security (spring-security-web) versions from 5.0.0 before 5.7.13, from 5.8.0 before 5.8.15, from 6.0.0 before 6.0.13, from 6.1.0 before 6.1.11, from 6.2.0 before 6.2.7, and from 6.3.0 before 6.3.4 are affected. In WebFlux applications that serve static resources and apply a non-permitAll authorization rule to them, an attacker can bypass those authorization rules to access the protected static resources. Upgrade to 5.7.13, 5.8.15, 6.0.13, 6.1.11, 6.2.7, 6.3.4, or a later fixed version. The source gives few details on any workaround.
