What the vulnerability does
The DICOM Support plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'dcm' shortcode in all versions up to, and including, 0.10.6 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
DICOM Support versions 0.10.6 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability affects the scope beyond the vulnerable component due to how the application processes user input. An attacker with low-level access can craft payloads that execute in other users' browsers, potentially compromising session data or performing unauthorized actions.
What an attacker can do
Inject and execute malicious JavaScript in other users' browsers to steal session data or perform actions on their behalf.
Potential impact on your site
Users' accounts and data are at risk if an authenticated attacker injects malicious scripts that execute in other users' sessions.
Conditions required to exploit
Attacker must have a low-privilege account on the application; no user interaction required from the victim.
