CVE-2026-26321

Estado: AnalizadaAlta (7.5)—

OpenClaw is a personal AI assistant. Prior to OpenClaw version 2026.2.14, the Feishu extension previously allowed `sendMediaFeishu` to treat attacker-controlled `mediaUrl` values as local filesystem paths and read them directly. If an attacker can influence tool calls (directly or via prompt injection), they may be able to exfiltrate local files by supplying paths such as `/etc/passwd` as `mediaUrl`. Upgrade to OpenClaw `2026.2.14` or newer to receive a fix. The fix removes direct local file reads from this path and routes media loading through hardened helpers that enforce local-root restrictions.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N/UI:N indica red sin privilegios. CWE-22 (path traversal) permite leer archivos locales (/etc/passwd) exfiltrando datos. T1005 por acceso directo a filesystem.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

Antes de la versión 2026.2.14 de OpenClaw, la extensión Feishu permitía a `sendMediaFeishu` tratar los valores `mediaUrl` controlados por el atacante como rutas del sistema de archivos local y leerlos directamente. Si un atacante puede influir en las llamadas a herramientas (directamente o mediante inyección de comandos), podría filtrar archivos locales proporcionando rutas como '/ etc / passwd' como «mediaUrl». Actualice a OpenClaw «2026.2.14» o una versión posterior para recibir una corrección. La corrección elimina la lectura directa de archivos locales de esta ruta y redirige la carga de medios a través de ayudantes reforzados que aplican restricciones de raíz local."
