Description

The Tainacan plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'get_file' function in all versions up to, and including, 0.21.7. The function is also vulnerable to directory traversal. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

Affected products

• Tainacan: before 0.21.8 — fixed in 0.21.8

How to fix

Upgrade to a fixed version: Tainacan 0.21.8. Check the vendor advisory for mitigations.
