CVE-2026-28446

Estado: ModificadaCrítica (9.2)—

OpenClaw versions prior to 2026.2.1 with the voice-call extension installed and enabled contain an authentication bypass vulnerability in inbound allowlist policy validation that accepts empty caller IDs and uses suffix-based matching instead of strict equality. Remote attackers can bypass inbound access controls by placing calls with missing caller IDs or numbers ending with allowlisted digits to reach the voice-call agent and execute tools.

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 de autenticación remota (AV:N, PR:N, UI:N) que permite bypass de controles de acceso sin requisitos de privilegios. Los atacantes alcanzan agentes de voz y ejecutan herramientas (tool execution), resultando en acceso no autorizado y ejecución de código.

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.
