Allocation of Resources Without Limits or Throttling

Overview websocket-driver is a websocket protocol handler with pluggable I/O. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via message compression through the hybi message handling in lib/websocket/driver/hybi.js. An attacker can make a...

GHSA-MP7J-QC5W-4988 websocket-driver: Resource limit bypass via message compression

Impact If this library is used in tandem 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. This is because this limit is checked against the message frames' length headers, which give the si...

websocket-driver: Message corruption via abuse of protocol length headers

Impact The frame format in draft versions of the WebSocket protocol includes a length header that allows an arbitrarily large integer to be encoded as a sequence of bytes with the high bit set. By sending an indefinite sequence of bytes with values 0x80 or above, a client can make the server pars...

websocket-driver: Memory exhaustion in HTTP header parser

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 memo...

CVE-2026-54458

WWBN AVideo is an open source video platform. Versions prior to 29.0 contain a stored DOM Cross-Site Scripting vulnerability in the YPTSocket plugin. Any unauthenticated remote attacker can execute arbitrary JavaScript in the authenticated origin of every administrator currently viewing a page th...

CVE-2026-54458

CVE-2026-54458 (AVideo YPTSocket XSS) affects WWBN’s AVideo with the YPTSocket plugin (versions prior to 29.0). The vulnerability is an unauthenticated stored DOM XSS: getWebSocket.json.php issues a signed WebSocket token; MessageSQLiteV2::onOpen reads webSocketSelfURI and page_title from the Web...

CVE-2026-59950

The MCP Python SDK, called mcp on PyPI, is a Python implementation of the Model Context Protocol MCP. Prior to 1.28.1, the deprecated mcp.server.websocket.websocketserver transport accepted WebSocket handshakes without applying Host or Origin header validation, leaving no SDK-level way to restric...

CVE-2026-49279 WWBN AVideo: Stored XSS via autoEvalCodeOnHTML Bypass in MessageSQLite WebSocket Handler (CVE-2026-43874 Bypass)

WWBN AVideo is an open source video platform. Versions 29.0 and below contain a Stored XSS vulnerability through the autoEvalCodeOnHTML parameter in the MessageSQLite WebSocket Handler. The MessageSQLite.php handler only strips autoEvalCodeOnHTML from $json'msg', but msgToResourceId reads from...

CVE-2026-49279

CVE-2026-49279 (WWBN AVideo) describes a stored XSS in the WebSocket messaging system. The vulnerability arises because MessageSQLite.php only strips autoEvalCodeOnHTML from json["msg"], while msgToResourceId() favors json over msg, allowing an attacker to place the payload in json and bypass san...
