      <title>CVE-2026-54490 — websocket-driver: Resource limit bypass via message compression</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-54490</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; faye websocket-driver-node&lt;/p&gt;
&lt;p&gt;websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, if this library is used with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size because the limit is checked against the message frames&amp;#39; length headers, which give the size of the compressed data, not the size after decompression in lib/websocket/driver/hybi.js. This can lead to applications accepting larger messages than expected and exceeding their intended resource usage. This issue is fixed in version 0.7.5.&lt;/p&gt;</description>
