CVE-2026-28482

Estado: AnalizadaAlta (8.4)—

OpenClaw versions prior to 2026.2.12 construct transcript file paths using unsanitized sessionId parameters and sessionFile paths without enforcing directory containment. Authenticated attackers can exploit path traversal sequences like ../../etc/passwd in sessionId or sessionFile parameters to read or write arbitrary files outside the agent sessions directory.

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:L + PR:L indica explotación local con privilegios de usuario (T1068). Path traversal permite leer/escribir archivos arbitrarios (T1005 + T1565); VC:H/VI:H confirma acceso y modificación de datos.

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.
