minimatch has ReDoS: matchOne() combinatorial backtracking via multiple non-adjacent GLOBSTAR segments

Summary matchOne performs unbounded recursive backtracking when a glob pattern contains multiple non-adjacent GLOBSTAR segments and the input path does not match. The time complexity is OCn, k -- binomial -- where n is the number of path segments and k is the number of globstars. With k=11 and...

GHSA-23C5-XMQV-RM74 minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions

Summary Nested extglobs produce regexps with nested unbounded quantifiers e.g. ?:?:a|b, which exhibit catastrophic backtracking in V8. With a 12-byte pattern a|b and an 18-byte non-matching input, minimatch stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes...

CVE-2026-27904

A flaw was found in minimatch. A remote attacker could exploit this vulnerability by providing a specially crafted glob expression with nested unbounded quantifiers. This could lead to catastrophic backtracking in the V8 JavaScript engine, causing the application to become unresponsive and...

Regular Expression Denial of Service (ReDoS)

Overview minimatch is a minimal matching utility. Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS. An attacker can cause excessive resource consumption and application unresponsiveness by supplying specially crafted nested extglob patterns that trigg...
