Overview

Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via evaluation of user-controlled Spring Expression Language (SpEL) expressions. An attacker can cause denial of service by supplying specially crafted SpEL expressions that trigger excessive CPU or memory consumption during expression evaluation, leading to application degradation or unavailability.
