This issue affects RepairBuddy: from n/a through 4.1121.

The RepairBuddy – Repair Shop CRM & Booking Plugin for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference due to missing capability checks on the wcuploadandsavesignaturehandler function in all versions up to, and including, 4.1116.
