Check if the SupportCandy plugin version is below 3.5.3. Look for unauthorized access to attachment download paths or unusual sequential ID requests in server logs. No specific commands are provided in the context.

Impact Analysis

Attackers could access sensitive customer data, such as support tickets and uploaded files, leading to privacy breaches. This may result in data leaks, reputational damage, or legal consequences depending on the exposed information.
