What the vulnerability does

01Description

The StreamWeasels YouTube Integration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'data-uuid' attribute in all versions up to, and including, 1.4.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers, potentially stealing session tokens or performing actions on their behalf. The vulnerability affects the entire application scope due to its network-accessible nature.
