Summary

Grav Flex Objects plugin from 1.4.0 before 1.4.17 contains an authorization bypass in its generic /api/v1/flex-objects/pages API routes. These routes check only directory-level admin.pages permissions and skip the Pages API's api.pages.read and api.pages.write permissions and page-level rules, which is classified as CWE-424. An authenticated non-super user with api.access and admin.pages or admin.configuration.pages permissions can read page source and frontmatter, modify content, or delete pages they are denied.

Description from the CNA

Grav Flex Objects plugin 1.4.0 before 1.4.17 contains an authorization bypass because its generic /api/v1/flex-objects/pages API routes check only directory-level admin.pages permissions, without enforcing the Pages API's api.pages.read/write permissions or page-level permissions rules. Authenticated non-super users with api.access and admin.pages or admin.configuration.pages permissions can read page source and frontmatter, modify content, or delete pages they are denied.
