CVE-2026-54465
websocket-driver: Memory exhaustion in HTTP header parser
描述
### Impact If this library is used to implement a WebSocket server on top of a TCP server (rather than an HTTP server or framework) using the `WebSocket::Driver.server()` method, or, if it is used to complement a WebSocket client, then 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. ### Patches The issue has been patched in version 0.8.1, by limiting the total size of HTTP request/response lines and headers accepted by the parser to 32 kB. All users should upgrade to this version. ### Workarounds No known workarounds exist. ### Acknowledgements This issue was discovered and reported by Pranjali Thakur, DepthFirst Security Research Team.
