Dependency Hierarchy: - firebase-admin-4.1.2.tgz (Root Library) - faye-websocket-0.9.3.tgz - websocket-driver-0.7.0.tgz - :x: **websocket-extensions-0.1.3.tgz** (Vulnerable Library)

Found in base branch: main

### Vulnerability Details

websocket-extensions npm module prior to 0.1.4 allows Denial of Service (DoS) via Regex Backtracking. The extension parser may take quadratic time when parsing a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. This could be abused by an attacker to conduct Regex Denial Of Service (ReDoS) on a single-threaded server by providing a malicious payload with the Sec-WebSocket-Extensions header.
