Summary

Spring Framework vulnerable to Denial of Service

Description

In Spring Framework versions 5.3.0 - 5.3.38 and older unsupported versions, it is possible for a user to provide a specially crafted Spring Expression Language (SpEL) expression that may cause a denial of service (DoS) condition. Older, unsupported versions are also affected.

Specifically, an application is vulnerable when the following is true:

• The application evaluates user-supplied SpEL expressions.
