The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Limited Privilege Escalation in all versions up to, and including, 4.0.3. This is due to the Gutenberg Register block passing the attacker-controlled Assigned Role attribute directly into the [wppb-register] shortcode without server-side authorization. The role guard in the form builder only downgrades roles that carry the manageoptions or removeusers capability, leaving the Editor role and other privileged non-Administrator roles completely unrestricted. This makes it possible for authenticated attackers with Author-level access and above to create new WordPress accounts bearing the Editor role (or any other role that lacks the two guarded capabilities).

The Profile Builder WordPress plugin from 4.0.0 to 4.0.4 does not enforce its reCAPTCHA verification on all comment submission paths, allowing authenticated users to bypass the anti-spam protection an administrator configured for the WordPress comment form.

The User Profile Builder WordPress plugin before 4.0.5 does not sanitise and escape one of its shortcode attributes before outputting it back in a redirect message, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks against higher-privileged users who submit the affected form.

The User Profile Builder WordPress plugin before 4.0.5 does not verify that a user is authorized to edit the specific account selected on its front-end Edit Profile form, allowing an Administrator of a Multisite subsite to change any other user's account email, including a Network Super Admin's, and take over that account through the password-reset flow.

Missing Authorization vulnerability in Cozmoslabs Paid Member Subscriptions paid-member-subscriptions allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Paid Member Subscriptions: from n/a through 3.1.2.

Incorrect Privilege Assignment vulnerability in Cozmoslabs Profile Builder profile-builder allows Privilege Escalation.This issue affects Profile Builder: from n/a through 4.0.4.

The User Profile Builder WordPress plugin before 4.0.1 does not escape the current page URL before outputting it in a JavaScript context on one of its admin pages, leading to Reflected Cross-Site Scripting against high-privilege users.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via First Name Field in all versions up to, and including, 4.0.3 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 is only exploitable when the Email Confirmation feature is enabled in Profile Builder.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.0.3 via the role parameter handled by the wppbaddmetatouseronactivation() function. The vulnerability exists because the activation handler passes the attacker-supplied role value directly to WPUser::setrole() with no allow-list validation, and the 4.0.3 reserved-name check exempts pre-existing form fields from the block, allowing a legacy field with meta-name role to persist and bridge attacker-controlled request input into the serialized signup record stored in wpsignups. This makes it possible for unauthenticated attackers to gain a fully activated WordPress administrator account by submitting role=administrator through the public [wppb-register] shortcode form and subsequently clicking the confirmation activation link. Exploitation requires the site to have a legacy form field with meta-name role carried over from before the 4.0.3 upgrade, email confirmation enabled, and open user registration — all stable site-state conditions once established.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'displayname' parameter in all versions up to, and including, 4.0.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload persists in wpcomments.commentauthor independently of the user account, so removing or changing the attacker's display name after the comment is posted does not neutralize the stored script.

Subscriber SQL Injection in Paid Member Subscriptions <= 3.1.1 versions.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Cozmoslabs TranslatePress translatepress-multilingual allows Stored XSS.This issue affects TranslatePress: from n/a through 3.3.6.

Unauthenticated Bypass Vulnerability in Paid Member Subscriptions <= 3.0.9 versions.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Avatar Field in all versions up to, and including, 4.0.2 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. The zero-length multipart file branch in wppbsaveavatarvalue() writes the raw request value directly to user meta, bypassing the wppbsaveattachmentid()/wppbverifyattachmentid() validation path; the stored payload is later adopted as a WordPress attachment URL and rendered unescaped by wppbdefaultfieldsmakeuploadbutton() when an administrator views the affected account.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Avatar Field in all versions up to, and including, 4.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable via a nonce-free GET request to /wp-admin/profile.php, requiring no profile-form submission; a Subscriber can plant the malicious attachment URL, which then executes when an administrator opens that user's Edit User screen.

The Paid Membership Subscriptions WordPress plugin before 3.1.0 does not verify the reCAPTCHA on its registration handler when a form field is absent from the request, allowing unauthenticated users to create accounts without solving the reCAPTCHA the site has enabled.

The Paid Membership Subscriptions WordPress plugin before 3.1.0 does not bind one of its unauthenticated payment actions to the requesting user, allowing someone who holds another member's in-flight payment identifier to delete that member's checkout state.

A vulnerability was found in Cozmoslabs Profile Builder Plugin up to 3.16.1 on WordPress. The impacted element is the function wppbajaxsimpleavatar of the file /wp-admin/admin-ajax.php of the component Avatar Simple Upload AJAX Handler. Performing a manipulation results in unrestricted upload. The attack is possible to be carried out remotely. The exploit has been made public and could be used. Upgrading to version 3.16.2 is sufficient to resolve this issue. It is suggested to upgrade the affected component.

Unauthenticated Cross Site Scripting (XSS) in Profile Builder Pro <= 3.15.0 versions.

The Profile Builder Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 3.14.5. This is due to the use of PHP's maybeunserialize() function on the attacker-controlled 'args' POST parameter within the wppbrequestuserspinsactioncallback() AJAX handler, which lacked any nonce verification, type checking, or input validation before deserialization. Because the handler was registered with both wpajax and wpajaxnopriv hooks, it was reachable by completely unauthenticated users. This makes it possible for unauthenticated attackers to inject arbitrary PHP objects into application memory.
