2DescriptionNVD
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.
AnalysisAI
ReDoS (Regular Expression Denial of Service) in Spring Framework's AntPathMatcher exposes applications to partial availability loss when an attacker can supply a crafted pattern string consumed by match(), matchStart(), or extractUriTemplateVariables(). Affected branches span all major actively maintained lines - 5.3.x through 7.0.x - covering a wide installed base across Java enterprise deployments. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the vulnerable application passes attacker-controlled data as the pattern argument (not the path argument) to one or more of: AntPathMatcher.match(), AntPathMatcher.matchStart(), or AntPathMatcher.extractUriTemplateVariables(). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.7 (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) correctly categorizes this as a low-severity issue requiring significant preconditions. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a Spring-based application endpoint that accepts a user-controlled string used as an AntPathMatcher pattern - for example, a custom URL routing API, a dynamic resource resolver, or a misconfigured security filter that evaluates user-provided path expressions. The attacker submits a specially crafted pattern string designed to trigger catastrophic backtracking in the regex engine, causing the processing thread to spin at high CPU for an extended period. … |
| Remediation | The primary remediation is to upgrade to the next patched release within the affected branch in use; consult the vendor advisory at https://spring.io/security/cve-2026-41848 for exact fixed version numbers, as they were not included in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
