CVE-2026-9595 webpack-dev-server vulnerable to HMR WebSocket interception via permissive user proxies

Impact: When a user-configured proxy on webpack-dev-server has a broad context e.g. / and ws: true, it also intercepts the dev server's own HMR WebSocket and forwards it to the proxy target. This leaks the browser's cookies and Origin header to the backend, bypasses the dev server's Host/Origin...

CVE-2026-9595

The CVE affects webpack-dev-server where a user-configured proxy with a broad context (e.g., /) and ws: true intercepts the dev server’s HMR WebSocket, forwarding it to the proxy target. This can leak cookies and Origin headers to the backend, bypass Host/Origin validation, and corrupt the HMR so...

CVE-2026-11624

The CVE-2026-11624 entry concerns the Model Context Protocol server where origin validation of the Origin header affects DNS rebinding risk. Before v0.25.0 there was no host validation; v0.25.0 introduces --allowed-hosts and --allowed-origins flags to specify permitted hosts at startup. Both flag...

PT-2026-49089

Name of the Vulnerable Software and Affected Versions Model Context Protocol versions prior to 0.25.0 Description Servers fail to validate the "Origin" header on incoming connections, which may allow DNS rebinding attacks. DNS rebinding is a method of bypassing the Same-Origin Policy to interact...
