My Sticky Elements < 2.3.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Bulk Lead Deletion

Description

The All-in-one Sticky Floating Contact Form, Call, Click to Chat, and 50+ Social Icon Tabs - My Sticky Elements plugin for WordPress is vulnerable to unauthorized data loss due to a missing capability check on the 'my_sticky_elements_bulks' function in all versions up to, and including, 2.3.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete all contact form leads stored by the plugin.
