What is CVE-2026-62670?

CVE-2026-62670 is a medium-severity missing authorization vulnerability in getgrav grav-plugin-flex-objects, published on 19 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

Grav Flex Objects Plugin allows you to build custom collections of objects. Prior to 1.4.3, the Grav Flex Objects Admin Next API requireFlexPermission() method in classes/Api/FlexApiController.php returns without denying access when a directory blueprint omits config.admin.permissions. An authenticated account with only api.access can use the index, show, create, update, delete, export, and media handlers for a permission-less directory even though the core admin.flex-object. authorization fallback would deny the same actions. This issue is fixed in version 1.4.3.
