Summary

The Premium Packages – Sell Digital Products Securely plugin for WordPress (versions up to and including 7.2.8) is vulnerable to Stored Cross-Site Scripting via the 'note' parameter due to insufficient input sanitization and output escaping. An authenticated attacker with subscriber-level access can inject scripts that execute when a user visits the injected page.

Risk Assessment

An attacker with a subscriber account can inject malicious scripts, potentially leading to session data theft or administrator account takeover.

Recommendation

Update the Premium Packages plugin to a version newer than 7.2.8 and monitor for unusual data in the 'note' field.

Original NVD description (English source)

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'note' parameter in all versions up to, and including, 7.2.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit bypasses tag-based filtering because the payload is stored as a hex-escaped sequence (e.g., \x3cimg onerror=...\x3e) that sanitize_textarea_field does not strip, and is only decoded back into a live HTML tag by stripcslashes() during admin rendering — after all sanitization has occurred.
