What the vulnerability does
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. 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.
Explanation of Vulnerability in Simple Terms
User Language Switch versions 1.6.10 and earlier contain a server-side request forgery vulnerability. An authenticated administrator can craft requests that cause the site to make HTTP requests to internal or external systems on the attacker's behalf. The impact is limited to reading non-sensitive data and making minor modifications. Update to a version newer than 1.6.10.
What an attacker can do
Make the site send HTTP requests to internal systems or external servers on the attacker's behalf.
Potential impact on your site
An admin account holder could use this to probe your internal network or exfiltrate non-sensitive data.
Conditions required to exploit
Attacker must have administrator-level access to the site.
