CVE-2026-72824

Estado: AplazadaAlta (8.7)—

The Grav API plugin (getgrav/grav-plugin-api) before 1.0.13 contains an API key scope-cap bypass in PagesController::guardTwigContent(). The Twig-toggle check uses a bare isSuperAdmin() gate that does not consult api_key_scopes, so a least-privilege API key scoped only to api.pages.write and minted on a super account can enable process.twig on a page save even though admin.pages_twig is intentionally outside the api.pages scope. When security.twig_content.process_enabled=true and editor_enabled=false, this allows Twig-in-content to execute server-side, resulting in server-side template injection (SSTI) and remote code execution.

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/PR:L permite explotación remota con privilegios locales (credenciales API de bajo nivel). La inyección Twig permite ejecución de código del lado del servidor (SSTI→RCE) y bypass de control de acceso (CWE-862).

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.
