CVE-2026-56253

Estado: AplazadaAlta (8.7)—

Capgo before 12.128.2 contains an improper access control vulnerability in the public.get_org_members RPC function that allows unauthenticated attackers to enumerate organization members. Attackers can invoke the endpoint using only the public sb_publishable_* key and an organization UUID to retrieve sensitive member information including email addresses, user IDs, roles, and pending invitations.

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.

Acceso de red sin autenticación (AV:N PR:N UI:N) a endpoint RPC expuesto; CWE-284 y divulgación de información sensible (emails, IDs, roles) de miembros de organización.

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.
