CVE-2026-96337

The ProfilePress (wp-user-avatar) plugin contains a Missing Authorization vulnerability caused by incorrectly configured access control. The issue affects versions from n/a through 4.17.3.

The ProfilePress plugin for WordPress up to version 4.17.4 is vulnerable to reflected XSS via the 'ppress_billing_address' parameter. Unauthenticated attackers can inject scripts that execute when a user clicks a crafted link.

The ProfilePress plugin for WordPress is vulnerable to sensitive information exposure in versions up to and including 4.17.4 via the get_user_profile_structure function. Authenticated attackers with subscriber-level access and above can extract other users' email addresses, login names, and registration dates. When the users_can_register option is enabled, unauthenticated attackers can also exploit this via registration.

The ProfilePress plugin for WordPress in all versions up to and including 4.17.2 is vulnerable to arbitrary shortcode execution. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode, allowing authenticated attackers with subscriber-level access and above to execute arbitrary shortcodes.

The ProfilePress (wp-user-avatar) WordPress plugin before 4.17.2 contains an unauthenticated remote code execution vulnerability. Attackers can install and activate arbitrary plugins by brute-forcing a weak 32-bit connect token via the ppress_connect_process AJAX handler, achieving PHP code execution as the web-server user.

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.

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.

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.

There is a Cross Site Scripting (XSS) vulnerability in ProfilePress versions <= 4.16.13 related to subscribers.

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.
