CVE-2026-74908

Grav plugin-api before version 1.0.15 has a script injection flaw: its SVG sanitizer checks only the exact extension "svg", so attackers with api.media.write permission can upload .svgz or .xhtml files with script payloads that bypass sanitization and execute in the site origin when accessed. CVS...

CVE-2026-74907

Grav before 2.0.15 uses string prefix matching instead of directory-boundary validation in the static asset server (index.php), allowing unauthenticated attackers to access sibling-directory files by requesting paths like assets-secret when assets is the base. Upgrade to Grav 2.0.15 or later to r...

PT-2026-76927

Grav before 2.0.15 contains an arbitrary file write vulnerability in the Blueprint dynamic-data bare-function validation that uses an incomplete denylist instead of a positive allowlist.

Grav: Unauthenticated denial of service via unbounded image derivative dimensions

CVE-2026-72829

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...

Grav API plugin versions before 1.0.13 fail to enforce API key scope caps in ConfigController super-scope gates, allowing scoped keys to write scheduler configuration. The scope cap is applied only inside requirePermission, while the scheduler and backups gates use a bare isSuperAdmin check that...

CVE-2026-72828

Grav Plugin API getgrav/grav-plugin-api before 1.0.13 fails to enforce API-key scope caps in InvitationsController.

CVE-2026-72825

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.

CVE-2026-72822

The getgrav/grav-plugin-api Composer package before 1.0.13 affected = 1.0.12 fails to enforce API key scope caps on the disable2fa endpoint. Unlike the sibling generate2fa endpoint, disable2fa authorizes the admin non-self path solely via ACL reads isSuperAdmin/hasPermission and never invokes...

CVE-2026-72824

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 apikeyscopes, so a least-privilege API key scoped only to api.pages.write and minted on a...

CVE-2026-72826

The getgrav/grav-plugin-api plugin before 1.0.13 fails to validate that the scopes of a newly created API key are a subset of the caller's scopes in createApiKey. The self-target path of requireApiKeyPermission requires only the baseline api.access scope, and the new key's scopes are read directl...
