CVE-2026-13355
Description détaillée
The Meta Box AIO plugin for WordPress is vulnerable to Privilege Escalation to Administrator in versions up to, and including, 3.11.0. This is due to a chained flaw: the populate_via_query_string() function in the mb-frontend-submission component unconditionally overrides the form's target object_id from the GET parameter 'rwmb_frontend_field_object_id' without any authorization check, and Form::process() lacks the user_can_edit() check present in render(), allowing unauthenticated attackers to overwrite the post_content of any page with an arbitrary shortcode via wp_update_post(); the mb-user-profile component then directly trusts the 'role' and 'auto_login' shortcode attributes in the injected [mb_user_profile_register] shortcode with no role validation. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator. The standalone plugins Meta Box Frontend Submission (in versions up to 4.5.6) and Meta Box User Profile (versions up to 3.11.0) are also affected.

Dernières Vulnérabilités
CVE-2026-94504
Ninja Forms 3.15.3 stores an anonymous non-RTE textarea value and renders it without safe HTML encoding in the legacy submission editor. An attacker can break out of the textarea with stored script. When an Administrator opens the attacker-known direct submission URL, the script runs in the WordPress admin origin.
CVE-2026-92438
The Ninja Forms WordPress plugin 3.15.3 does not escape submitted form field values before outputting them on the submission edit screen in the admin area, which could allow unauthenticated users to submit values through a public form that then execute in the browser of any high-privileged user who reviews the submission.
CVE-2026-91827
The Ninja Forms WordPress plugin 3.15.3 does not prevent user-submitted form field values from being deserialised when an administrator later exports form submissions to CSV, allowing unauthenticated attackers to perform PHP Object Injection; if a suitable POP chain is present via another installed plugin or theme, this can lead to actions such as arbitrary file operations or remote code execution.
