CVE-2026-41851 Details
Description
Applications which accept user-supplied Spring Expression Language (SpEL) expressions may be vulnerable to a Denial of Service (DoS) attack if the evaluation of a SpEL expression triggers unbounded cache growth. 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.
A denial-of-service vulnerability has been identified in Spring Framework versions 7.0.0 through 7.0.7, 6.2.0 through 6.2.18, 6.1.0 through 6.1.27, and 5.3.0 through 5.3.48. This vulnerability arises in applications that accept user-supplied Spring Expression Language (SpEL) expressions and cache the parsed expressions. When these conditions are met, an attacker can exploit the vulnerability by causing unbounded cache growth, leading to memory exhaustion and a denial-of-service condition after a high volume of processing, typically involving millions of evaluations.
Users of affected versions should upgrade to the fixed version. The following upgrade options are available: - For Spring Framework 7.0.x, upgrade to 7.0.8 (OSS) or 7.0.7.1 (Commercial). - For Spring Framework 6.2.x, upgrade to 6.2.19 (OSS) or 6.2.18.1 (Commercial). - For Spring Framework 6.1.x, upgrade to 6.1.28 (Commercial). - For Spring Framework 5.3.x, upgrade to 5.3.49 (Commercial).
