- CVE-2026-75824, 30 Sep 2026
- The User Frontend WordPress plugin before 4.3.12 does not check whether the site allows user registration before creating an account, allowing unauthenticated users to create accounts on sites where registration is disabled. The created account receives the site's default role. CVE record
- CVE-2026-75823, 30 Sep 2026
- The User Frontend WordPress plugin before 4.3.12 does not prevent tampering with the role assigned by its registration form, allowing unauthenticated users to register with a higher privileged role, such as Editor. This affects installations running a PHP build where the sodium extension is unavailable, and where a registration page has been configured. The administrator role cannot be obtained this way. CVE record
- CVE-2026-17563, 2 Sep 2026
- The User Frontend WordPress plugin before 4.3.11 does not enforce its subscription-purchase requirement when processing frontend post submissions, only when rendering the form, allowing unauthenticated users to create and, depending on the form's configuration, immediately publish posts through forms restricted to paying subscribers. CVE record
- CVE-2026-19116, 2 Sep 2026
- The User Frontend WordPress plugin before 4.3.11 does not prevent user-supplied field values from being deserialized when a submitted post is reopened in its frontend editing form, allowing authenticated users with subscriber-level access and above to perform PHP Object Injection, which may lead to remote code execution when a suitable gadget chain is present on the site. CVE record
- CVE-2026-14558, 28 Aug 2026
- The User Frontend WordPress plugin before 4.3.10 does not properly validate field type definitions and deserialises user-controlled post metadata when rendering submitted posts, allowing users with Editor-level access and above to inject arbitrary PHP objects, which can lead to remote code execution when a suitable POP chain is present on the site. CVE record
- CVE-2026-14567, 28 Aug 2026
- The User Frontend WordPress plugin before 4.3.10 does not restrict access to its user directory search endpoint, allowing unauthenticated attackers to retrieve the email address and phone number of every registered user, including administrators. CVE record
- CVE-2026-12418, 9 Jul 2026
- The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.7 via the 'wpuf_files_data' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to overwrite the post_title, post_content, and post_excerpt of any arbitrary post on the site, including posts authored by administrators. Exploitation requires access to any WPUF post submission form; this is achievable by users with no WordPress role, as the wpuf_submit_post AJAX action is gated only by a nonce with no capability check for the downstream post-edit operation. CVE record
- CVE-2026-12406, 9 Jul 2026
- The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.3.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to delete arbitrary media attachments whose post_author is 0, such as guest and registration-form uploads, via the wpuf_file_del AJAX action. This is exploitable by unauthenticated visitors on any site where a WPUF shortcode is rendered on a front-end page, as this causes the valid wpuf_nonce value to be localized into publicly accessible JavaScript objects (wpuf_upload and wpuf_frontend), satisfying the sole access control gate. CVE record
- CVE-2026-5459, 8 Jul 2026
- The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.1 via the payment_page() function due to missing validation on the 'user_id' user controlled key. This makes it possible for unauthenticated attackers to activate a free subscription pack for any user on the site, overwriting their existing paid subscription and causing loss of paid features. CVE record
- CVE-2026-5127, 8 May 2026
- The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to Deserialization of Untrusted Data in versions up to, and including, 4.3.1 This is due to insufficient input validation and type checking on the wpuf_files parameter during form submission, combined with unconditional deserialization via maybe_unserialize() when displaying post content. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary PHP objects, which can be leveraged to execute arbitrary code, delete arbitrary files, or perform other malicious actions if a POP chain is present on the target system. CVE record
- CVE-2026-2233, 16 Mar 2026
- The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the draft_post() function in all versions up to, and including, 4.2.8. This makes it possible for unauthenticated attackers to modify arbitrary posts (e.g. unpublish published posts and overwrite the contents) via the 'post_id' parameter. CVE record
- CVE-2026-1565, 26 Feb 2026
- The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to arbitrary file uploads due to incorrect file type validation in the 'WPUF_Admin_Settings::check_filetype_and_ext' function and in the 'Admin_Tools::check_filetype_and_ext' function in all versions up to, and including, 4.2.8. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE record
- CVE-2025-14047, 2 Jan 2026
- The Registration, User Profile, Membership, Content Restriction, User Directory, and Frontend Post Submission - WP User Frontend plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'Frontend_Form_Ajax::submit_post' function in all versions up to, and including, 4.2.4. This makes it possible for unauthenticated attackers to delete attachment. CVE record
- CVE-2021-24649, 21 Nov 2022
- The WP User Frontend WordPress plugin before 3.5.29 uses a user supplied argument called urhidden in its registration form, which contains the role for the account to be created with, encrypted via wpuf_encryption(). This could allow an attacker having access to the AUTH_KEY and AUTH_SALT constant (via an arbitrary file access issue for example, or if the blog is using the default keys) to create an account with any role they want, such as admin CVE record
- CVE-2021-25076, 24 Jan 2022
- The WP User Frontend WordPress plugin before 3.5.26 does not validate and escape the status parameter before using it in a SQL statement in the Subscribers dashboard, leading to an SQL injection. Due to the lack of sanitisation and escaping, this could also lead to Reflected Cross-Site Scripting CVE record
What to do if you run User Frontend
If you run User Frontend, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
