What the vulnerability does
The WP Popup Magic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name' parameter of the [wppum_end] shortcode in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. 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
WP Popup Magic versions 1.0.0 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Site administrators should update to a version newer than 1.0.0 as soon as a patch becomes available.
What an attacker can do
Inject and execute malicious JavaScript in the site, affecting other users and site functionality.
Potential impact on your site
Attackers with user accounts can inject scripts that compromise other users' sessions, steal data, or deface site content.
Conditions required to exploit
Attacker must have a low-privilege user account (e.g., subscriber or contributor role) on the WordPress site.
