Easy Digital Downloads Stored Cross-Site Scripting Vulnerability in WordPress

A stored cross-site scripting vulnerability has been identified in the Easy Digital Downloads plugin for WordPress, specifically in the eCommerce Payments and Subscriptions made easy version 3.3.2 and prior. This vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level access to inject arbitrary web scripts into pages. The injected scripts are executed when a user accesses the compromised page. This issue is present only in multi-site installations where unfiltered_html has been disabled.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users are advised to update the Easy Digital Downloads plugin to version 3.3.3 or a newer patched version.
