Machine-written summary

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

Apereo CAS management webapp support (org.apereo.cas:cas-management-webapp-support) versions up to and including 5.2.6 contain a code injection flaw in the saveService function, which handles Groovy code. The source describes the attack as remote but of high complexity and difficult to exploit, and says a public exploit exists. No fixed version is listed, so the source gives no upgrade path.
