Received Received - Intake
Algorithmic DoS in Spring Framework via SpEL Expression Evaluation

Publication date: 2026-06-09

Last updated on: 2026-06-09

Assigner: VMware

Description
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.
