What the vulnerability does
The Groups plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'groups_group_info' shortcode in all versions up to, and including, 3.10.0 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.
Explanation of Vulnerability in Simple Terms
Groups versions up to 3.10.0 contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users on the site. The vulnerability exists in how user input is processed and displayed without proper sanitization. An attacker with low-level access can craft payloads that execute in other users' browsers, potentially stealing session data or performing actions on their behalf.
What an attacker can do
Inject JavaScript code that runs in other users' browsers and steals their session data or performs actions as them.
Potential impact on your site
Authenticated users can be compromised; attackers may steal admin sessions or modify site content through victim accounts.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required from the victim.
