CVE-2026-13272——
———IBM Verify Identity Access is missing origin validation which could allow a remote attacker to perform operations as the victim and potentially launch further attacks against the systems.15hCVE-2026-714168.8 ALT7.0%
——2Headroom 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.4dCVE-2026-88061—15.6%
——5career-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 0.8.0.5dCVE-2026-851839.3 CRÍ4.8%
——1Taipy configures its socket.io server with wildcard CORS origin and credential flag enabled, allowing any web page to establish credentialed WebSocket connections to victim applications. Attackers can open socket.io sessions from arbitrary domains and invoke state variable modifications and action callbacks without CSRF protection.5dCVE-2026-15580—8.7%
——3vault token disclosure via unvalidated postMessage vulnerability in N-able PassPortal allows Authentication Abuse.
This issue affects the PassPortal browser extension: before 3.49.6.7dCVE-2026-599508.1 ALT13.9%
——4The 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 1.28.1.60d
