Applications that evaluate user-supplied Spring Expression Language (SpEL) expressions are vulnerable to an Algorithmic Denial of Service (DoS). By providing a specially crafted expression, an attacker can trigger excessive resource consumption during evaluation, leading to application degradation or unavailability.
Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.
Weakness
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
