Summary
The ProfilePress plugin for WordPress up to version 4.16.11 has a vulnerability allowing unauthorized membership payment bypass. Missing ownership verification on the change_plan_sub_id parameter in process_checkout() allows authenticated attackers (subscriber level and above) to reference another user's active subscription, manipulate proration calculations, and obtain paid lifetime membership plans without payment.

Recommendation
Update the ProfilePress plugin to version 4.16.12 or later.
Other vulnerabilities in ProfilePress
See all- CVE-2026-19848Medium
The ProfilePress WordPress plugin before 4.17.1 does not strip shortcodes from two of its profile fields before rendering them on public pages, allowing unauthenticated attackers to store shortcodes that are then executed when the page is viewed, disclosing a chosen user's email address, login and registration date.
- CVE-2026-18385Medium
The ProfilePress plugin for WordPress up to version 4.16.19 is vulnerable to arbitrary shortcode execution. This is due to improper validation before running do_shortcode. Authenticated attackers with subscriber-level access can execute arbitrary shortcodes, and partial mitigations can be bypassed via various render paths.
- CVE-2026-13352High
The ProfilePress plugin for WordPress up to version 4.16.18 is vulnerable to arbitrary file upload. The allowed_mime_types function globally adds executable extensions (.exe, .apk, .msi) to the MIME allowlist without scoping to digital product contexts. This allows authenticated attackers with author-level access or above to upload executable files, leading to remote code execution.
- CVE-2026-41556Medium
There is a Cross Site Scripting (XSS) vulnerability in ProfilePress versions <= 4.16.13 related to subscribers.
- CVE-2026-3309Medium
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.
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 unauthorized membership payment bypass in all versions up to, and including, 4.16.11. This is due to a missing ownership verification on the `change_plan_sub_id` parameter in the `process_checkout()` function. This makes it possible for authenticated attackers, with subscriber level access and above, to reference another user's active subscription during checkout to manipulate proration calculations, allowing them to obtain paid lifetime membership plans without payment via the `ppress_process_checkout` AJAX action.
