CVE-2026-92783

Estado: AplazadaAlta (7.2)—

Yeti through 2.11.0 fails to validate caller permissions in the DELETE /api/v2/rbac/{id} endpoint, allowing users with read access to delete access control relationships. Attackers can revoke the owner's grant and permanently lock legitimate owners out of objects.

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 con PR:L permite explotación remota de servicio REST (T1210). Eliminación no autorizada de relaciones RBAC revoca permisos de propietarios (T1078) y deniega acceso legítimo (T1531).

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.
