Detailsinfo

A vulnerability was found in isaacs minimatch up to 11.0.0. It has been classified as problematic. Affected is the function firstPhasePreProcess of the file src/index.ts of the component Glob Pattern Processing. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. CVE summarizes:

minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Prior to 11.0.1, src/index.ts implements firstPhasePreProcess() so that, at optimizationLevel 2 or higher, it repeatedly expands attacker-controlled **/.. pattern segments inside a fixpoint loop, allowing generated globParts entries to be processed and expanded again. secondPhasePreProcess() then compares the expanded entries pairwise, so a short malicious glob can cause excessive CPU and memory consumption during pattern compilation. This issue is fixed in version 11.0.1.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-118764 since 10/28/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.

Upgrading to version 11.0.1 eliminates this vulnerability.
