CVE-2026-41848
Spring Framework Denial of Service via AntPathMatcher
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.
