CVE-2026-93690
uri-js through 4.4.1 contains a denial of service vulnerability in the removeDotSegments function that loops infinitely when a path segment begins with Unicode line or paragraph separators. Attackers can trigger this by calling removeDotSegments directly or through normalize/resolve functions with IRI handling enabled, causing the Node.js event loop to block indefinitely until heap exhaustion.
