Vulnerability Details

@isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process. This issue has been patched in version 5.0.1.

Vulnerability Details

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 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 this to minutes. This is the most severe finding: it is triggered by the default "minimatch()" API with no special options, and the minimum viable pattern is only 12 bytes. The same issue affects "+()" extglobs equally. Versions 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 fix the issue.

Vulnerability Details

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 3.1.3, "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 O(C(n, k)) -- binomial -- where "n" is the number of path segments and "k" is the number of globstars. With k=11 and n=30, a call to the default "minimatch()" API stalls for roughly 5 seconds. With k=13, it exceeds 15 seconds. No memoization or call budget exists to bound this behavior. Any application where an attacker can influence the glob pattern passed to "minimatch()" is vulnerable. The realistic attack surface includes build tools and task runners that accept user-supplied glob arguments (ESLint, Webpack, Rollup config), multi-tenant systems where one tenant configures glob-based rules that run in a shared process, admin or developer interfaces that accept ignore-rule or filter configuration as globs, and CI/CD pipelines that evaluate user-submitted config files containing glob patterns. An attacker who can place a crafted pattern into any of these paths can stall the Node.js event loop for tens of seconds per invocation. The pattern is 56 bytes for a 5-second stall and does not require authentication in contexts where pattern input is part of the feature. Versions 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.3 fix the issue.

Vulnerability Details

minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Versions prior to 10.2.1, 3.1.3, 4.2.4, 5.1.7, 6.2.1, 7.4.7, 8.0.5, and 9.0.6 are vulnerable to Regular Expression Denial of Service (ReDoS) when a glob pattern contains many consecutive * wildcards followed by a literal character that doesn't appear in the test string. Each * compiles to a separate [^/]*? regex group, and when the match fails, V8's regex engine backtracks exponentially across all possible splits. The time complexity is O(4^N) where N is the number of * characters. With N=15, a single minimatch() call takes ~2 seconds. With N=34, it hangs effectively forever. Any application that passes user-controlled strings to minimatch() as the pattern argument is vulnerable to DoS.
This issue has been fixed in versions 10.2.1, 3.1.3, 4.2.4, 5.1.7, 6.2.1, 7.4.7, 8.0.5, and 9.0.6.
