          "value": "The User Frontend \u2013 Membership, User Registration, User Profile, User Directory \u0026 Content Restriction with Frontend Post Submission plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.3.13 via the `post_content` parameter of the `submit_post()` function. The vulnerability exists because the protected-shortcode blocklist guard inspects the `sanitize_textarea_field()` copy of the submitted `post_content`, while the copy actually persisted to the database is processed through `wp_kses()`, whose `wp_kses_no_null()` step strips C0 control bytes \u2014 allowing an attacker to inject a single `\\x01` byte inside the `[wpuf-registration]` tag name to defeat the `strpos()` blocklist check while the clean, functional shortcode is stored verbatim; `strip_shortcodes()` does not neutralize the stored shortcode either, because the Frontend container that registers it via `add_shortcode()` is only instantiated when `is_admin()` is false, and `admin-ajax` requests have `is_admin() === true`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a `[wpuf-registration role=\"editor\"]` shortcode into a published post, causing a live Editor-role registration form to be rendered publicly on the frontend that any visitor \u2014 or the attacker themselves \u2014 can submit to mint a WordPress Editor account with an immediately active privileged session when the default `autologin_after_registration` setting is enabled."
