CVE-2026-63750

SurrealDB before 3.1.0 is affected: the SURREAL_WEBSOCKET_MAX_MESSAGE_SIZE limit is not applied to anonymous /sql WebSocket connections, allowing attackers to buffer unbounded frames in per-connection read buffers. Attackers can stream large WebSocket frames across multiple concurrent connections...

CVE-2026-63747 SurrealDB before 3.1.0 Denial of Service via malformed RPC use

SurrealDB versions before 3.1.0 contain a denial of service vulnerability in the RPC use handler that panics when db is set without a namespace. Unauthenticated attackers can send a malformed WebSocket message to the /rpc endpoint to crash the server process...

CVE-2026-63747

SurrealDB prior to 3.1.0 contains a denial-of-service condition in the RPC use handler. When a request sets db without a namespace, a malformed WebSocket message sent to the /rpc endpoint can cause the server process to panic, leading to service disruption. The issue is exploitable by unauthentic...

webpack-dev-server: webpack-dev-server: Information disclosure and denial of service via improper proxy configuration

A flaw was found in webpack-dev-server. When a user configures a proxy with a broad context, such as '/', and enables WebSocket ws: true forwarding, the development server's own Hot Module Replacement HMR WebSocket can be intercepted. This interception leads to the leakage of the browser's cookie...

PT-2026-61566

Name of the Vulnerable Software and Affected Versions SurrealDB versions prior to 3.1.0 Description Anonymous WebSocket connections to the '/sql' endpoint do not enforce the SURREAL WEBSOCKET MAX MESSAGE SIZE limit. This allows attackers to buffer unbounded frames in the per-connection read buffe...

PT-2026-61563

Name of the Vulnerable Software and Affected Versions SurrealDB versions prior to 3.1.0 Description A denial of service issue exists in the RPC use handler that causes a panic when the db variable is set without a namespace. Unauthenticated attackers can crash the server process by sending a...

CVE-2026-63760: Uncontrolled Recursion

SurrealDB before 3.1.0 fails to enforce the configured recursion depth limit in the value and JSON parser when processing nested braces, brackets, or parentheses. Unauthenticated attackers can send deeply nested JSON payloads to the WebSocket /rpc endpoint to exhaust server memory and crash the...

CVE-2026-63750: Allocation of Resources Without Limits or Throttling

SurrealDB versions before 3.1.0 fail to apply the SURREALWEBSOCKETMAXMESSAGESIZE limit to anonymous /sql WebSocket connections, allowing attackers to buffer unbounded frames in the per-connection read buffer. Attackers can stream WebSocket frames larger than the configured limit across multiple...

Allocation Of Resources Without Limits

websocket-driver is vulnerable to Allocation Of Resources Without Limits. The vulnerability is due to parsing arbitrarily long WebSocket frame length headers into unbounded arbitrary-precision integers, which allows an attacker to consume excessive memory and cause the host process to run out of...

Denial Of Service (DoS)

websocket-driver is vulnerable to Denial Of Service DoS. The vulnerability is due to the lack of limits on processing HTTP request or response headers during the WebSocket handshake, which allows an attacker to send an endless list of headers and exhaust the receiving process's memory, resulting ...

Denial Of Service (DoS)

websocket-driver is vulnerable to Denial Of Service DoS. The vulnerability is due to validating only the compressed message size instead of the decompressed size when using the permessage-deflate extension, which allows an attacker to send compressed messages that expand beyond the configured...

Improper Origin Validation

MCP Python SDK is vulnerable to Improper Origin Validation. The vulnerability is due to the WebSocket transport accepting handshake requests without validating the Host or Origin headers, which allows an attacker to establish unauthorized cross-origin WebSocket connections...

Directory Traversal

Overview @fastify/http-proxy is a proxy http requests, for Fastify Affected versions of this package are vulnerable to Directory Traversal via the WebSocket routing. An attacker can access unintended upstream endpoints by sending crafted WebSocket upgrade requests containing path traversal...

Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization in the RequestApproval function of the WebSocket Approval Endpoint in execapproval.go. An attacker can gain unauthorized access to resources or perform actions with insufficient authorization by sending crafted...
