CVE-2026-118764 · Severity: medium · CVSS 4 · Published 2026-10-29

minimatch is a JavaScript library that converts glob patterns (like file path wildcards) into regular expressions for pattern matching. A malicious glob pattern can cause the library to consume excessive CPU and memory during compilation, potentially causing a denial of service when applications process untrusted glob patterns.

Technologies: [minimatch (npm)](https://junglewise.ai/threats/technologies/minimatch). Vendors: [Isaacs](https://junglewise.ai/threats/vendors/isaacs), [npm](https://junglewise.ai/threats/vendors/npm).

## How to fix

- minimatch (npm): upgrade to 11.0.1 or later

  ```sh
  npm install minimatch@11.0.1
  ```


## Technical details

A ReDoS (Regular Expression Denial of Service) vulnerability exists in the firstPhasePreProcess() function, where attacker-controlled **/../ pattern segments are repeatedly expanded in a fixpoint loop at optimization levels 2 or higher, generating excessive globParts entries. The secondPhasePreProcess() function then performs pairwise comparison of these entries, leading to quadratic CPU and memory consumption. The vulnerability requires the application to process attacker-supplied glob patterns with high optimization levels enabled.

## Affected products
