Vulnerability Description
An authenticated SQL Injection vulnerability (CWE-89) exists in the Koha staff interface in the /cgi-bin/koha/suggestion/suggestion.pl endpoint due to improper validation of the displayby parameter used by the GetDistinctValues functionality.

Successful exploitation may lead to full compromise of the backend database, including disclosure or modification of stored data.
