What the vulnerability does
The Get Youtube Subs plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘channel', 'layout', and 'subs_count’ parameters in all versions up to, and including, 3.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Get Youtube Subs versions 3.5 and earlier contain a cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers, potentially stealing session data or performing actions on their behalf. The vulnerability affects the entire application scope due to how the flaw is processed.
What an attacker can do
Inject malicious scripts that run in other users' browsers and steal their session data or perform actions as them.
Potential impact on your site
