Detailsinfo

A vulnerability, which was classified as critical, has been found in GetGrav Grav up to 1.0.12. This issue affects the function isSuperAdmin of the file /reports/twig-content/allowlist of the component ReportsController. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The getgrav/grav-plugin-api plugin before 1.0.13 contains an API-key scope cap bypass in the POST /reports/twig-content/allowlist endpoint (ReportsController). The endpoint enforces requirePermission('api.config.write') followed by a bare isSuperAdmin() check instead of requireSuper(). Because isSuperAdmin() reads access.api.super directly and never consults api_key_scopes, a least-privilege API key scoped to api.config.write minted on a super account passes the gate, allowing an attacker to append attacker-chosen tokens to the security.twig_sandbox allowlist (persisted to user/config/security.yaml). Widening the allowlist turns any subsequent Twig-in-content render into an SSTI/RCE sink.
