CVE-2026-62667
Published:August 19, 2026
Updated:September 24, 2026
Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, the Grav API plugin ApiKeyManager::generateKey() stores a declared scopes array, but ApiKeyAuthenticator::authenticate() does not read keyData[scopes] and returns the owning user's complete identity. AbstractApiController::requirePermission() consequently evaluates the full user ACL, so a key issued for a read-only scope can perform every write, delete, and administrative operation available to the owner. This issue is fixed in version 1.0.6.
