CVE-2026-56222

Estado: AplazadaAlta (8.6)—

Capgo before 12.128.2 contains an authorization bypass vulnerability in POST /private/role_bindings that fails to verify app_id ownership during app-scoped role binding creation. An attacker with administrative privileges in one organization can create role bindings targeting applications owned by other organizations, enabling unauthorized read and modification of victim applications.

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).
