CVE-2026-0745
The User Language Switch plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.6.10 due to missing URL validation on the 'download_language()' function.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
Description

This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
