Severity
Summary
OpenClaw is a personal AI assistant. Prior to version 2026.2.14, authenticated attackers can read arbitrary files from the Gateway host by supplying absolute paths or path traversal sequences to the browser tool's `upload` action. The server passed these paths to Playwright's `setInputFiles()` APIs without restricting them to a safe root. An attacker must reach the Gateway HTTP surface (or otherwise invoke the same browser control hook endpoints); present valid Gateway auth (bearer token / password), as required by the Gateway configuration (In common default setups, the Gateway binds to loopback and the onboarding wizard generates a gateway token even for loopback); and have the `browser` tool permitted by tool policy for the target session/context (and have browser support enabled). If an operator exposes the Gateway beyond loopback (LAN/tailnet/custom bind, reverse proxy, tunnels, etc.), the impact increases accordingly. Starting in version 2026.2.14, the upload paths are now confined to OpenClaw's temp uploads root (`DEFAULT_UPLOAD_DIR`) and traversal/escape paths are rejected.

"value": "OpenClaw es un asistente personal de IA. Antes de la versi\u00f3n 2026.2.14, los atacantes autenticados pueden leer archivos arbitrarios del host Gateway proporcionando rutas absolutas o secuencias de salto de ruta a la acci\u00f3n \u0027upload\u0027 de la herramienta del navegador. El servidor pas\u00f3 estas rutas a las API \u0027setInputFiles()\u0027 de Playwright sin restringirlas a una ra\u00edz segura. Un atacante debe alcanzar la superficie HTTP del Gateway (o invocar de otro modo los mismos puntos finales de gancho de control del navegador); presentar autenticaci\u00f3n Gateway v\u00e1lida (token de portador / contrase\u00f1a), seg\u00fan lo requiera la configuraci\u00f3n del Gateway (En configuraciones predeterminadas comunes, el Gateway se enlaza a loopback y el asistente de incorporaci\u00f3n genera un token de gateway incluso para loopback); y tener la herramienta \u0027browser\u0027 permitida por la pol\u00edtica de herramientas para la sesi\u00f3n/contexto objetivo (y tener el soporte del navegador habilitado). Si un operador expone el Gateway m\u00e1s all\u00e1 de loopback (LAN/tailnet/enlace personalizado, proxy inverso, t\u00faneles, etc.), el impacto aumenta en consecuencia. A partir de la versi\u00f3n 2026.2.14, las rutas de carga ahora est\u00e1n confinadas a la ra\u00edz de cargas temporales de OpenClaw (\u0027DEFAULT_UPLOAD_DIR\u0027) y las rutas de salto/escape son rechazadas."
