CVE-2026-55768 GoAccess WebSocket Server: Signed 32 bit truncation of the 64 bit frame length causes a remote pre-authentication denial of service

GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in nix systems or through the browser. Prior to version 1.11, the built-in WebSocket server narrows a 64-bit extended frame length into the signed 32-bit WSFrame.payloadlen field before enforcing the maximum...

CVE-2026-55768

GoAccess (WebSocket server) before version 1.11 is affected by a vulnerability where a 64‑bit extended frame length is truncated to a signed 32‑bit WSFrame.payloadlen before max frame size is enforced. This allows an unauthenticated remote client to trigger an extremely large allocation (~18 exab...

GHSA-GMFW-G93R-VG53 Open WebUI: Unauthenticated WebSocket Access to Collaborative Document Handlers (ydoc:awareness:update, ydoc:document:leave)

Summary The Socket.IO server is configured with alwaysconnect=True lines 78, 91 in backend/openwebui/socket/main.py and the connect handler line 329 never rejects unauthenticated connections. Two Ydoc event handlers have zero authentication checks, allowing unauthenticated clients to interact wit...

PT-2026-63317

Impact If this library is used to implement a WebSocket server on top of a TCP server, by using the WebSocket::Driver.server method, then a client can cause the server to crash by sending a Host header that is not a valid host:port string. When this happens, a URI::InvalidURIError exception is...

CVE-2026-54465 websocket-driver: Memory exhaustion in HTTP header parser

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...

libevent: Libevent: Remote denial of service via unbounded memory accumulation in WebSocket server

A flaw was found in Libevent. An unauthenticated remote client can exploit this vulnerability by repeatedly sending fragmented WebSocket frames to the Libevent WebSocket server. Due to a lack of a total message-size limit, these fragmented frames accumulate in memory without bound, leading to...

CVE-2026-54490: Allocation of Resources Without Limits or Throttling

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...
