Title
Network-AI 5.0.0 before 5.15.2 Cross-Site WebSocket Hijacking via DashboardServer
Summary
Network-AI 5.0.0 before 5.15.2 contains a cross-site WebSocket hijacking vulnerability in DashboardServer that allows remote attackers to read live agent topology because handleUpgrade performs no Origin or token validation. Attackers can lure a victim running the dashboard to a malicious page that opens a WebSocket to the loopback dashboard and exfiltrates agent IDs, roles, task descriptions, and token budgets.

Title
Punk versions from 0.48 before 0.55 for Perl route Extended CONNECT requests to any GET route without an Origin check in ps_serve_one
Summary
Punk versions from 0.48 before 0.55 for Perl route Extended CONNECT requests to any GET route without an Origin check in ps_serve_one. On HTTP/2 and HTTP/3 a WebSocket handshake arrives as an Extended CONNECT, which is matched as a GET and so reaches every GET route, API operation and mount. The Origin check runs only when a websocket route matches. On this transport the handler's status is the handshake response, and a 2xx accepts it. A cross-origin page can open a WebSocket to any path and learn from its open or error event whether that path returns 2xx.

CVE-2026-88061 (GCVE-0-2026-88061)

Vulnerability from cvelistv5 – Published: 2026-09-10 19:08 – Updated: 2026-09-15 15:36

Title
career-ops: Local dashboard API accepted cross-origin and non-loopback requests, allowing unauthenticated command execution
Summary
career-ops is an open-source AI-assisted job search and application management tool. Prior to 0.8.0, the career-ops local web dashboard web/ exposed command-spawning and user-file-writing /api routes without validating request origin or restricting clients to loopback addresses. A malicious page in another browser tab could send cross-origin localhost requests while the dashboard was running, and a dashboard bound beyond loopback could receive direct requests from the local network. Both paths allowed unauthenticated command execution as the dashboard user, but npm installations were unaffected because web/ is excluded from the published package. This issue is fixed in version 0.8.0.

CVE-2026-77363 (GCVE-0-2026-77363)

Vulnerability from cvelistv5 – Published: 2026-10-12 17:45 – Updated: 2026-10-13 16:03

Title
obsidian-tc Streamable HTTP transport permits cross-origin loopback vault access
Summary
obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, the Streamable HTTP transport does not validate the Host or Origin header or enable DNS-rebinding protection. When the documented loopback configuration uses auth.mode set to none, a malicious web page can send requests to the local MCP endpoint and receive unrestricted vault access through the http-local caller. Version 1.3.1 fixes the vulnerability by enabling host, origin, and DNS-rebinding validation.

CVE-2026-71416 (GCVE-0-2026-71416)

Vulnerability from cvelistv5 – Published: 2026-09-11 13:34 – Updated: 2026-09-11 14:33
VLAI
Title
Headroom vulnerable to Cross-Site WebSocket Hijacking (CSWSH)
Summary
Headroom compresses data before the data reaches a large language model. Prior to version 0.35.0, the Headroom WebSocket server does not validate the `Origin` header of incoming client WebSocket requests before forwarding the request to the upstream server, allowing malicious WebSocket clients to perform arbitrary LLM requests without authentication. This can be exploited by a malicious WebSocket client executed in a traditional or headless browser such as lightpanda, if the browser has access to the Headroom proxy and the OpenAI API key is stored in the `OPENAI_API_KEY` environment variable. Version 0.35.0 fixes the issue.

CVE-2026-67405 (GCVE-0-2026-67405)

Title
RabbitMQ: CSWSH on Web-STOMP / Web-MQTT (no Origin validation)
Summary
RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, Neither the Web-MQTT handler (deps/rabbitmq_web_mqtt/src/rabbit_web_mqtt_handler.erl:104) nor the Web-STOMP handler (deps/rabbitmq_web_stomp/src/rabbit_web_stomp_handler.erl:102) validates the Origin header on the WebSocket upgrade. Under ssl_cert_login=true, the browser presents the client certificate automatically, so an attacker's JavaScript running in the victim's browser can authenticate as the victim. Preconditions include The non-default configuration use_http_auth=true (Web-STOMP) or ssl_cert_login=true (both plugins) must be enabled. The issue is harmless under the default in-band CONNECT credential configuration.. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0.

CVE-2026-59950 (GCVE-0-2026-59950)

Vulnerability from cvelistv5 – Published: 2026-07-15 20:08 – Updated: 2026-07-17 12:28

Title
MCP Python SDK: WebSocket server transport does not support Host/Origin validation
Summary
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.websocket_server transport accepted WebSocket handshakes without applying Host or Origin header validation, leaving no SDK-level way to restrict which origins could connect to applications that exposed that transport. This issue is fixed in version 1.28.1.
Severity
7.6 (High)

Title
Midscene Bridge Server - Session Hijack via Unauthenticated WebSocket
Summary
Midscene Bridge Server through 1.10.3, fixed in commit 86f4118, contains a missing authentication and CORS misconfiguration vulnerability that allows unauthenticated remote attackers to hijack active bridge sessions by opening a cross-origin WebSocket connection to the local Socket.IO server, which performs no Origin header validation and requires no authentication token. Attackers can connect from any web page visited by the victim to seize the single-client slot, intercept and inject automation commands, exfiltrate command-payload data, or unconditionally terminate the server by supplying the MIDSCENE_BRIDGE_SIGNAL_KILL query parameter.

CVE-2026-57111 (GCVE-0-2026-57111)

Title
Apache Helix REST: Permissive CORS Configuration in REST API Allows Unrestricted Cross-Origin
Summary
Permissive Cross-Origin Resource Sharing (CORS) in the REST API (helix-rest, org.apache.helix.rest.server.filters.CORSFilter) in Apache Helix through 2.0.0 on all platforms allows a remote attacker controlling a web page visited by an authorized user to read responses from and issue cross-origin requests to administrative REST endpoints via a cross-origin request from an arbitrary origin, since the filter unconditionally returns Access-Control-Allow-Origin: * together with Access-Control-Allow-Credentials: true and reflects arbitrary Access-Control-Request-Method / Access-Control-Request-Headers values in preflight responses. Users are recommended to upgrade to version 2.0.1, which fixes this issue.

Mitigation
Implementation

Enable CORS-like access restrictions by verifying the 'Origin' header during the WebSocket handshake.

Mitigation
Implementation

Use a randomized CSRF token to verify requests.

Mitigation
Implementation

Use TLS to securely communicate using 'wss' (WebSocket Secure) instead of 'ws'.

Mitigation
Architecture and Design Implementation

Require user authentication prior to the WebSocket connection being established. For example, the WS library in Node has a 'verifyClient' function.

Mitigation
Implementation

Leverage rate limiting to prevent against DoS. Use of the leaky bucket algorithm can help with this.

Mitigation
Implementation

Use a library that provides restriction of the payload size. For example, WS library for Node includes 'maxPayloadoption' that can be set.

Mitigation
Implementation

Treat data/input as untrusted in both directions and apply the same data/input sanitization as XSS, SQLi, etc.
