      <title>CVE-2026-54465 — websocket-driver: Memory exhaustion in HTTP header parser</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-54465</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; faye websocket-driver-ruby&lt;/p&gt;
&lt;p&gt;websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, when websocket-driver is used to implement a WebSocket server on top of a TCP server using WebSocket::Driver.server() or to complement a WebSocket client, a peer can make a single connection consume an unbounded amount of memory by sending an HTTP request or response with a never-ending list of headers. This can lead to the receiving process running out of memory. This issue is fixed in version 0.8.1.&lt;/p&gt;</description>
