What is CVE-2026-72829?
CVE-2026-72829 is a high-severity vulnerability in getgrav grav, published on 14 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.13 contains an API-key scope-cap bypass in UsersController's create() and update() methods. These methods enforce the scope cap only for api.users.write, but gate super-privilege grants on a bare isSuperAdmin() check that reads access.api.super directly without consulting the key's scopes. As a result, an api.users.write-scoped key minted on a super account can set access.api.super or assign a super-granting group to mint or promote a full super account, then authenticate as that account for uncapped administrative privileges.
Weakness: CWE-269
