minimatch 10.2.6 contains an attacker-controlled pattern amplification in firstPhasePreProcess() when optimizationLevel >= 2. researcher: Reid Downing (b1nv0id) files: - src/index.ts: 690-770 - src/index.ts: 780-796 issue: input-controlled growth of globParts during first-phase preprocessing, followed by quadratic second-phase processing. the **/../ transformation clones a globparts entry and appends the clone to the same globparts array: this occurs inside a do...while (didSomething) fixpoint loop, allowing generated entries to be processed again. the expanded globparts array is subsequently processed by secondPhasePreProcess(), which performs pairwise comparisons: an attacker who can supply a glob pattern can therefore cause additional pattern entries to be generated during preprocessing, followed by quadratic pairwise processing, resulting in excessive cpu and memory consumption.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.

The check returns affected, not affected, or incomplete. It does not guess a version that is missing from the record.

  • npm minimatch< 11.0.1
  • npm minimatch<11.0.1
  • npm minimatch>= 7.0.0, < 11.0.1
