Exposure of Sensitive Information to an Unauthorized Actor vulnerability in User Meta user-meta.This issue affects User Meta: from n/a through 3.0.

The Display post meta, term meta, comment meta, and user meta plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post metadata in versions up to, and including, 0.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Cross-Site Request Forgery (CSRF) vulnerability in User Meta Manager plugin <= 3.4.9 versions.

Reflected Cross-Site Scripting (XSS) vulnerability in Jason Lau User Meta Manager plugin <= 3.4.9 versions.

The User Meta WordPress plugin before 2.4.4 does not validate the filepath parameter of its um_show_uploaded_file AJAX action, which could allow low privileged users such as subscriber to enumerate the local files on the web server via path traversal payloads

The User Meta WordPress plugin before 2.4.3 does not sanitise and escape the Form Name, as well as Shared Field Labels before outputting them in the admin dashboard when editing a form, which could allow high privilege users to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed

The User Meta Shortcodes WordPress plugin through 0.5 registers a shortcode that allows any user with a role as low as contributor to access other users metadata by specifying the user login as a parameter. This makes the WP instance vulnerable to data extrafiltration, including password hashes
