NVD Description

Note: Versions mentioned in the description apply only to the upstream node-uri-js package and not the node-uri-js package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

uri-js through 4.4.1 contains an improper UTF-8 decoding vulnerability in pctDecChars() that decodes invalid and overlong percent-encoded sequences into ASCII metacharacters. Attackers can craft percent-encoded payloads to bypass platform decoder validation and inject path traversal or CRLF sequences that downstream consumers process without filtering.
