[Security] Bump websocket-extensions from 0.1.3 to 0.1.4 Bumps [websocket-extensions](https://github.com/faye/websocket-extensions-node) from 0.1.3 to 0.1.4. **This update includes a security fix.** <details> <summary>Vulnerabilities fixed</summary> <p><em>Sourced from <a href="https://github.com/advisories/GHSA-g78m-2chm-r7qv">The GitHub Security Advisory Database</a>.</em></p> <blockquote> <p><strong>Regular Expression Denial of Service in websocket-extensions (NPM package)</strong></p> <h3>Impact</h3> <p>The ReDoS flaw allows an attacker to exhaust the server's capacity to process incoming requests by sending a WebSocket handshake request containing a header of the following form:</p> <pre><code>Sec-WebSocket-Extensions: a; b="\c\c\c\c\c\c\c\c\c\c ... </code></pre> <p>That is, a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. The parser takes exponential time to reject this header as invalid, and this will block the processing of any other work on the same thread. Thus if you are running a single-threaded server, such a request can render your service completely unavailable.</p> <h3>Patches</h3> <p>Users should upgrade to version 0.1.4.</p> <h3>Workarounds</h3> </tr></table> ...
