CVE-2026-110664 Details
Description
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.
A stored cross-site scripting vulnerability has been identified in the Premium Packages – Sell Digital Products Securely plugin for WordPress, affecting all versions through 7.2.8. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with subscriber-level access and above to inject arbitrary scripts into pages. These scripts execute when a user accesses the compromised page. The vulnerability exploits tag-based filtering by storing the payload as a hex-escaped sequence, which bypasses the sanitization applied by 'sanitize_textarea_field'. The injected script is only decoded into a live HTML tag during admin rendering, after all sanitization has been applied.
Users are advised to update the Premium Packages WordPress plugin to version 7.3.0 or later.
