Received Received - Intake
Regular Expression Denial of Service in Spring Framework

Publication date: 2026-06-09

Last updated on: 2026-06-09

Assigner: VMware

Description
Applications may be vulnerable to a Regular Expression Denial of Service (ReDoS) attack if an attacker is able to provide a pattern which is then directly or indirectly supplied to one of the following methods in AntPathMatcher: match(String pattern, String path), matchStart(String pattern, String path), extractUriTemplateVariables(String pattern, String path). 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.

Compliance Impact

The provided information does not specify any direct impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.

Detection Guidance

There are no specific detection commands or network/system scanning methods provided for this vulnerability.

The recommended approach to address this vulnerability is to upgrade affected Spring Framework versions to the fixed releases: 7.0.8, 6.2.19, 6.1.28, or 5.3.49.

Executive Summary

CVE-2026-41848 is a Regular Expression Denial of Service (ReDoS) vulnerability in the Spring Framework, specifically in the AntPathMatcher class.

The vulnerability occurs when an attacker provides a malicious regular expression pattern that is used by methods such as match, matchStart, or extractUriTemplateVariables. This malicious pattern can cause excessive CPU usage, leading to system slowdown or denial of service.

The affected versions include Spring Framework 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.

Impact Analysis

This vulnerability can impact you by allowing an attacker to cause a denial of service condition through excessive CPU consumption.

If an attacker supplies a crafted regular expression pattern to the vulnerable methods, it can cause the application to slow down significantly or become unresponsive, potentially disrupting service availability.

Mitigation Strategies

To mitigate this vulnerability, users should upgrade their Spring Framework versions to the fixed releases.

  • Upgrade to Spring Framework 7.0.8 if using 7.0.0 through 7.0.7.
  • Upgrade to Spring Framework 6.2.19 if using 6.2.0 through 6.2.18.
  • Upgrade to Spring Framework 6.1.28 if using 6.1.0 through 6.1.27.
  • Upgrade to Spring Framework 5.3.49 if using 5.3.0 through 5.3.48.

No additional mitigation steps are required beyond upgrading.
