What the vulnerability does
The FuseDesk plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's fusedesk_newcase shortcode in all versions up to, and including, 6.8 due to insufficient input sanitization and output escaping on the 'emailtext' attribute. 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
FuseDesk versions 6.8 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts affecting other users. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. An attacker with low-level credentials can inject code that executes in other users' browsers without requiring user interaction.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and steal their session data or perform actions on their behalf.
Potential impact on your site
Authenticated users' accounts and data are at risk; attackers can hijack sessions or modify content visible to other users.
Conditions required to exploit
Attacker must have a low-privilege account on the FuseDesk instance; no user interaction required from victims.
