CVE-2026-85658
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
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.
Risk Assessment
An authenticated low-privileged attacker can execute arbitrary shortcodes, potentially leading to data disclosure, content modification, or privilege escalation depending on available shortcodes. This bypasses the plugin's intended access controls.
Recommendation
Update the ProfilePress plugin to a version newer than 4.17.2 as soon as it becomes available. Until a fix is released, consider restricting new user registrations or reviewing account roles, and monitor for unusual subscriber activity.
Other vulnerabilities in ProfilePress
See all- CVE-2026-66047High
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.
- 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.
- CVE-2026-3445High
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.
