    Inefficient Algorithmic Complexity

    Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the uniqs helper and index-membership checks in src/parser.js when parsing flat selectors (e.g. .a.a.a...) containing a large number of class or ID tokens. The original implementation uses Array.indexOf inside a filter callback and repeated linear scans of the hasClass/hasId arrays, producing quadratic time complexity proportional to the number of tokens. An attacker who can supply selector input to the parser can trigger CPU exhaustion by providing a long flat selector, pinning a CPU core and causing the process to become unresponsive.

    How to fix Inefficient Algorithmic Complexity?

    Upgrade postcss-selector-parser to version 7.1.6 or higher.
