GHSA-g3hv-75wg-m249: minimatch (CVE-2026-118764)

Package	Ecosystem	Affected	Fixed in
minimatch	npm	>=7.0.0, <11.0.1	11.0.1

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

minimatch versions before 11.0.1 are affected by a denial-of-service issue in pattern preprocessing, which the source describes as occurring when optimizationLevel is 2 or higher. An attacker who can supply a glob pattern to the library can cause it to generate many extra pattern entries, which then require quadratic pairwise processing, leading to excessive CPU and memory use. The source states the issue is fixed in version 11.0.1, so users should upgrade to minimatch 11.0.1 or later.
