What is CVE-2024-9891?

The Multiline files upload feature of the Contact Form 7 plugin for WordPress is affected by a vulnerability that could allow authenticated attackers with Subscriber-level access or above to deactivate the plugin. This is due to a missing capability check in the mfcf7_zl_custom_handle_deactivation_plugin_form_submission() function, present in all versions up to and including 2.8.1.
