Technical description

The ONLYOFFICE Docs plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization within its oo.callback REST endpoint in versions 1.1.0 to 2.2.0. The plugin’s permission callback only verifies that the supplied, encrypted attachment ID maps to an existing attachment post, but does not verify the requester’s identity or capabilities. This makes it possible for unauthenticated attackers to log in as an arbitrary user.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
