Advisory
Source description from Wordfence Intelligence, credited to blue0x1.
The weDocs: AI Powered Knowledge Base, Docs, Documentation, Wiki & AI Chatbot plugin for WordPress is vulnerable to unauthorized modification or loss of data due to a missing capability check on the 'wedocs_user_documentation_handling_capabilities' function in all versions up to, and including, 2.1.16. This makes it possible for authenticated attackers, with Subscriber-level access and above, to edit any documentation post. The vulnerability was partially patched in version 2.1.16.
