OpenCATS from version 0.9.1a contains an SQL injection vulnerability in DataGrid filter handling that allows authenticated attackers to inject SQL through crafted filters targeting the non-filterable Tags column in the Candidates DataGrid. Attackers can bypass column filterable restrictions by manipulating filter requests to execute arbitrary SQL queries against the database.
