Descriptions

In spring framework versions prior to 5.2.24 release+ ,5.3.27+ and 6.0.8+ , it is possible for a user to provide a specially crafted SpEL expression that may cause a denial-of-service (DoS) condition.

A flaw was found in Spring Framework. Certain versions of Spring Framework's Expression Language were not restricting the size of Spring Expressions. This could allow an attacker to craft a malicious Spring Expression to cause a denial of service on the server.
