CVE-2026-65895Public exploitNetwork attack vector

Site-wide security control changes via omitted scope

Published Jul 23, 2026 · Updated Jul 23, 2026

Missing authorization in Grav API Plugin before 1.0.10 allows remote authenticated users to alter site-wide API security settings. ConfigController::assertScopeAllowed() omits plugins/api from both privileged-scope lists, so PATCH /config/plugins/api accepts rate-limit and CORS changes from api.config.write credentials. The caller needs an authenticated API credential with api.config.write but not api.super; disabling throttling enables credential guessing, while widened CORS is not a demonstrated session-theft path.
