FKIE_CVE-2024-9891

Vulnerability from fkie_nvd - Published: 2024-10-16 02:15 - Updated: 2026-06-17 08:25
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Summary
The Multiline files upload for contact form 7 plugin for WordPress is vulnerable to unauthorized plugin deactivation due to a missing capability check on the mfcf7_zl_custom_handle_deactivation_plugin_form_submission() function in all versions up to, and including, 2.8.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to deactivate the plugin and send a custom reason from the site.
