- CVE-2026-80072, 13 Sep 2026
- The User Registration & Membership WordPress plugin before 5.2.8 does not validate the destination of a post-login redirect before redirecting, allowing unauthenticated attackers to redirect visitors to an arbitrary external URL, which can be abused for phishing. CVE record
- CVE-2026-86406, 13 Sep 2026
- The User Registration & Membership WordPress plugin before 5.2.8 does not check the capability of the user making a membership purchase, and does not validate the payment method or the plan submitted with it, allowing any authenticated user such as a subscriber to be granted the WordPress role attached to a paid plan without paying for it. Where the site owner has mapped a plan to a privileged role, this leads to privilege escalation up to administrator. CVE record
- CVE-2026-86407, 13 Sep 2026
- The User Registration & Membership WordPress plugin before 5.2.8 does not verify that the visitor requesting its membership confirmation page owns the account named in the request, nor that any registration or purchase has taken place, allowing unauthenticated users to retrieve another user's email address, profile fields, role and membership order details. Exploitation requires the site owner to have added a user smart tag to that page's configurable message, which the shipped default does not contain. CVE record
- CVE-2026-80071, 13 Sep 2026
- The User Registration & Membership WordPress plugin before 5.2.8 does not properly restrict who may author a membership plan or validate the plan a user attaches to their own account, allowing authenticated users with Author-level access and above to assign themselves an arbitrary role and escalate their privileges to Administrator. CVE record
- CVE-2026-79995, 28 Aug 2026
- The User Registration & Membership WordPress plugin before 5.2.5 does not verify that the account whose pending email change is being cancelled belongs to the user making the request, allowing authenticated users with Subscriber-level access and above to cancel any other user's in-progress email change, including an administrator's. CVE record
- CVE-2026-79996, 28 Aug 2026
- The User Registration & Membership WordPress plugin before 5.2.6 does not perform a capability check when saving its login settings, allowing authenticated users who have been granted a User Registration & Membership WordPress plugin before 5.2.6 management capability but not full administrator access to change arbitrary site options and escalate their privileges to administrator. CVE record
- CVE-2026-16736, 5 Aug 2026
- The User Registration & Membership WordPress plugin before 5.2.6 does not enforce the site's registration-disabled setting when processing registration-form submissions, allowing unauthenticated users to create new accounts even when the administrator has turned off open registration. CVE record
- CVE-2026-11961, 17 Jul 2026
- The User Registration & Membership WordPress plugin before 5.2.3 does not validate that the membership tier submitted during public registration is one of the tiers allowed by the registration form before assigning that tier's associated user role, allowing unauthenticated users to register into an arbitrary published membership tier and obtain its role - up to administrator when such a tier exists. CVE record
- CVE-2026-11966, 17 Jul 2026
- The User Registration & Membership WordPress plugin before 5.2.3 does not perform a capability check for unauthenticated callers on one of its membership payment actions and acts on a caller-supplied user identifier, allowing unauthenticated attackers to delete recently-registered, payment-pending user accounts. CVE record
- CVE-2026-11963, 13 Jul 2026
- The User Registration & Membership WordPress plugin before 5.2.2 does not perform an authorization check on a membership-upgrade action and derives the user to modify from a caller-supplied identifier instead of the current user, allowing any authenticated user such as a subscriber to change another user's WordPress role and membership tier. CVE record
- CVE-2026-11964, 13 Jul 2026
- The User Registration & Membership WordPress plugin before 5.2.2 does not verify the authenticity of incoming payment-provider webhook notifications before acting on them, allowing unauthenticated attackers to forge a payment-approved event and activate a paid membership subscription without completing a real payment. CVE record
- CVE-2026-11965, 2 Jul 2026
- The User Registration & Membership WordPress plugin before 5.2.0 does not enforce payment completion before activating a paid membership subscription, allowing unauthenticated users (after self-registering an account through the open registration flow) to obtain an active subscription on any paid plan without paying and access the gated content. CVE record
- CVE-2026-1869, 26 Jun 2026
- The User Registration & Membership - Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to unauthorized modification of data due to missing validation checks in the confirm_payment() function in all versions up to, and including, 5.2.0. This makes it possible for unauthenticated attackers to bypass payment processing and activate paid memberships. CVE record
- CVE-2026-7651, 28 May 2026
- The User Registration & Membership - Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.5. This is due to missing ownership validation on a user-controlled attachment ID, allowing the plugin to store and subsequently delete arbitrary media attachments without verifying that the referenced attachment belongs to the requesting user. This makes it possible for authenticated attackers, with subscriber-level access and above, to permanently delete arbitrary media attachments uploaded by any other user, including administrators. CVE record
- CVE-2026-6145, 14 May 2026
- The User Registration & Membership plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 5.1.5. This is due to the is_admin_creation_process() method relying solely on the presence of action=createuser in the $_REQUEST superglobal without performing any authentication or capability check. This makes it possible for unauthenticated attackers to bypass the admin approval requirement when registering new accounts via the fallback submission path. CVE record
- CVE-2026-3601, 5 May 2026
- The User Registration & Membership plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `embed_form_action()` function in all versions up to, and including, 5.1.4. This makes it possible for authenticated attackers, with Contributor-level access and above, to append shortcode content to arbitrary pages they do not own or have permission to edit. CVE record
- CVE-2026-6203, 13 Apr 2026
- The User Registration & Membership plugin for WordPress is vulnerable to Open Redirect in versions up to and including 5.1.4. This is due to insufficient validation of user-supplied URLs passed via the 'redirect_to_on_logout' GET parameter before redirecting users. The `redirect_to_on_logout` GET parameter is passed directly to WordPress's `wp_redirect()` function instead of the domain-restricted `wp_safe_redirect()`. While `esc_url_raw()` is applied to sanitize malformed URLs, it does not restrict the redirect destination to the local domain, allowing an attacker to craft a specially formed link that redirects users to potentially malicious external URLs after logout, which could be used to facilitate phishing attacks. CVE record
- CVE-2026-1865, 8 Apr 2026
- The User Registration & Membership - Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to SQL Injection via the ‘membership_ids[]’ parameter in all versions up to, and including, 5.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. CVE record
- CVE-2026-4056, 24 Mar 2026
- The User Registration & Membership plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the Content Access Rules REST API endpoints in versions 5.0.1 through 5.1.4. This is due to the `check_permissions()` method only checking for `edit_posts` capability instead of an administrator-level capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to list, create, modify, toggle, duplicate, and delete site-wide content restriction rules, potentially exposing restricted content or denying legitimate user access. CVE record
- CVE-2026-1492, 3 Mar 2026
- The User Registration & Membership - Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to improper privilege management in all versions up to, and including, 5.1.2. This is due to the plugin accepting a user-supplied role during membership registration without properly enforcing a server-side allowlist. This makes it possible for unauthenticated attackers to create administrator accounts by supplying a role value during membership registration. CVE record
- CVE-2026-2356, 26 Feb 2026
- The User Registration & Membership - Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.2 via the 'register_member' function, due to missing validation on the 'member_id' user controlled key. This makes it possible for unauthenticated attackers to delete arbitrary user accounts that newly registered on the site who has the 'urm_user_just_created' user meta set. CVE record
- CVE-2026-1779, 26 Feb 2026
- The User Registration & Membership plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.1.2. This is due to incorrect authentication in the 'register_member' function. This makes it possible for unauthenticated attackers to log in a newly registered user on the site who has the 'urm_user_just_created' user meta set. CVE record
- CVE-2025-14976, 10 Jan 2026
- The User Registration & Membership - Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.4.8. This is due to missing or incorrect nonce validation on the 'process_row_actions' function with the 'delete' action. This makes it possible for unauthenticated attackers to delete arbitrary post via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE record
- CVE-2025-13367, 15 Dec 2025
- The User Registration & Membership - Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple shortcode attributes in all versions up to, and including, 4.4.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2025-9085, 6 Sep 2025
- The User Registration & Membership plugin for WordPress is vulnerable to SQL Injection via the 's' parameter in version 4.3.0. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.

CVE record
- CVE-2025-3281, 6 May 2025
- The User Registration & Membership - Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.2.1 via the create_stripe_subscription() function, due to missing validation on the 'member_id' user controlled key. This makes it possible for unauthenticated attackers to delete arbitrary user accounts that have registered through the plugin. CVE record
- CVE-2025-2594, 22 Apr 2025
- The User Registration & Membership WordPress plugin before 4.1.3 does not properly validate data in an AJAX action when the Membership Addon is enabled, allowing attackers to authenticate as any user, including administrators, by simply using the target account's user ID. CVE record
- CVE-2025-2563, 14 Apr 2025
- The User Registration & Membership WordPress plugin before 4.1.2 does not prevent users to set their account role when the Membership Addon is enabled, leading to a privilege escalation issue and allowing unauthenticated users to gain admin privileges CVE record
- CVE-2025-3282, 12 Apr 2025
- The User Registration & Membership - Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.3 via the user_registration_membership_register_member() due to missing validation on the 'membership_id' user controlled key. This makes it possible for unauthenticated attackers to update any user's membership to any other active or non-active membership type. CVE record
- CVE-2025-3292, 12 Apr 2025
- The User Registration & Membership - Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.3 via the user_registration_update_profile_details() due to missing validation on the 'user_id' user controlled key. This makes it possible for unauthenticated attackers to update other user's passwords, if they have access to the user ID and email. CVE record
- CVE-2025-1511, 28 Feb 2025
- The User Registration & Membership - Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 4.0.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. CVE record
- CVE-2024-4958, 1 Jun 2024
- The User Registration - Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'import_form_action' function in versions up to, and including, 3.2.0.1. This makes it possible for authenticated attackers, with contributor-level permissions and above, to import a registration form with a default user role of administrator. If an administrator approves or publishes a post or page with the shortcode to the imported form, any user can register as an administrator. CVE record
- CVE-2024-3295, 2 May 2024
- The User Registration - Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the profile_pic_remove function in versions up to, and including, 3.1.5. This makes it possible for unauthenticated attackers to delete any media file. CVE record
- CVE-2024-2417, 2 May 2024
- The User Registration - Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the form_save_action() function in all versions up to, and including, 3.1.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the registration form and make the default registration role administrator. This subsequently allows the attacker to register an account as an administrator on the site. CVE record
- CVE-2024-1720, 7 Mar 2024
- The User Registration - Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Display Name' parameter in all versions up to, and including, 3.1.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability requires social engineering to successfully exploit, and the impact would be very limited due to the attacker requiring a user to login as the user with the injected payload for execution. CVE record
- CVE-2023-5228, 6 Nov 2023
- The User Registration WordPress plugin before 3.0.4.2 does not sanitize and escape some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup). CVE record
- CVE-2023-3342, 13 Jul 2023
- The User Registration plugin for WordPress is vulnerable to arbitrary file uploads due to a hardcoded encryption key and missing file type validation on the 'ur_upload_profile_pic' function in versions up to, and including, 3.0.2. This makes it possible for authenticated attackers with subscriber-level capabilities or above to upload arbitrary files on the affected site's server which may make remote code execution possible. This was partially patched in version 3.0.2 and fully patched in version 3.0.2.1. CVE record
- CVE-2023-3343, 13 Jul 2023
- The User Registration plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.0.1 via deserialization of untrusted input from the 'profile-pic-url' parameter. This allows authenticated attackers, with subscriber-level permissions and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. CVE record
- CVE-2022-3912, 12 Dec 2022
- The User Registration WordPress plugin before 2.2.4.1 does not properly restrict the files to be uploaded via an AJAX action available to both unauthenticated and authenticated users, which could allow unauthenticated users to upload PHP files for example. CVE record
- CVE-2021-24654, 4 Oct 2021
- The User Registration WordPress plugin before 2.0.2 does not properly sanitise the user_registration_profile_pic_url value when submitted directly via the user_registration_update_profile_details AJAX action. This could allow any authenticated user, such as subscriber, to perform Stored Cross-Site attacks when their profile is viewed CVE record
What to do if you run User Registration & Membership
If you run User Registration & Membership, 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.
