What the vulnerability does
The EDD Download Info plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'edd_download_info_link' shortcode in all versions up to, and including, 1.1 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
EDD Download Info versions 1.1 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, potentially impacting other users or site functionality. An attacker with low-level site access can exploit this without user interaction to inject code that executes in other users' browsers.
What an attacker can do
Inject malicious JavaScript that executes in other users' browsers, potentially stealing data or performing actions on their behalf.
Potential impact on your site
Authenticated users with low privileges can inject scripts affecting other site visitors or administrators, compromising user sessions or site integrity.
Conditions required to exploit
Attacker must have a low-privilege account on the site (e.g., subscriber or contributor role).
