Affected versions: *-5.1.5

Vulnerability type: CWE-639 Authorization Bypass Through User-Controlled Key

Affected software, patched versions and attribution

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.

User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder: Currently marked unpatched

Affected versions: *-5.1.5

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

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.

User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder: Currently marked unpatched

Affected versions: *-5.1.4

Vulnerability type: CWE-601 URL Redirection to Untrusted Site ('Open Redirect')

Affected software, patched versions and attribution

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.

Affected versions: *-5.1.4

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

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.
