Low risk33th percentile - higher than 33% of all known CVEs
Summary
The ProfilePress plugin for WordPress up to version 4.16.11 allows arbitrary shortcode execution. This is because billing field values from the checkout process are interpolated into shortcode template strings without proper sanitization. Unauthenticated attackers can execute arbitrary shortcodes by submitting crafted billing field values during checkout.
Risk Assessment
Risk of remote code execution on the WordPress site, which could lead to site takeover, data theft, or malware distribution.
Recommendation
Update the ProfilePress plugin to version 4.16.12 or later. Restrict access to the checkout process for untrusted users.
Original NVD description (English source)
The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 4.16.11. This is due to the plugin allowing user-supplied billing field values from the checkout process to be interpolated into shortcode template strings that are subsequently processed without proper sanitization of shortcode syntax. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes by submitting crafted billing field values during the checkout process.
