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...

CVE-2026-27904 minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions

minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Prior to version 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4, nested extglobs produce regexps with nested unbounded quantifiers e.g. ?:?:a|b, which exhibit catastrophic...

CVE-2026-27493

n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, a second-order expression injection vulnerability existed in n8n's Form nodes that could allow an unauthenticated attacker to inject and evaluate arbitrary n8n expressions by submitting crafted form...
