CVE-2026-43534

Estado: AnalizadaCrítica (9.3)—

OpenClaw before 2026.4.10 contains an input validation vulnerability that allows external hook metadata to be enqueued as trusted system events. Attackers can supply malicious hook names to escalate untrusted input into higher-trust agent context.

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.

Vulnerabilidad remota de validación de entrada (CWE-345) sin autenticación en OpenClaw: ataque de aplicación expuesta (T1190). Metadata maliciosa de hooks entra en contexto de confianza → manipulación de cadena de suministro (T1195.002). Escalación a agente de mayor confianza implica obtención de cr
