There is no fixed version for uri-js.
Overview
uri-js is a RFC 3986/3987 compliant, scheme extendable URI/IRI parsing/validating/resolving library for JavaScript.
Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via pctDecChars(), which decodes invalid and overlong percent-encoded sequences into ASCII metacharacters. An attacker can craft percent-encoded payloads to bypass platform decoder validation and inject path traversal or CRLF sequences that downstream consumers process without filtering.
