## Description

A local file enumeration was found in Keyfactor SignServer versions prior to 7.3.2 .The property VISIBLE_SIGNATURE_CUSTOM_IMAGE_PATH, which exists in the PDFSigner and the PAdESSigner, can be set to any path without any restrictions by an admin user. In the case that the provided path points to an existing file, readable by the user running the application server, but is not a recognized image format, it will return this as an error to the clientside, confirming the existences of the file.

## What to do
