Description
The W3 Total Cache WordPress plugin before 2.10.6 does not confine a media-import file copy to the document root, nor enforce an effective file-type restriction on it, allowing users with the Author role or higher to plant content that, once an administrator runs the import, copies an arbitrary server-readable file into a publicly served directory, exposing it to unauthenticated retrieval.
Affected products
- W3 Total Cache: before 2.10.6 — fixed in 2.10.6
How to fix
Upgrade to a fixed version: W3 Total Cache 2.10.6. Check the vendor advisory for mitigations.
