CVE-2026-62235Network attack vector

Authenticated object CRUD via fail-open permission check

Published Jul 17, 2026 · Updated Jul 17, 2026

Broken access control in Grav Flex-Objects before 1.4.3 allows remote authenticated users to perform unauthorized CRUD through the REST API. FlexApiController::requireFlexPermission returns without denying access when a directory blueprint omits config.admin.permissions. An api.access account can create, read, update, delete, or export objects only from directories with that permission-less configuration.
