Technical details
An SQL injection vulnerability exists in OpenCATS starting from version 0.9.1a within the DataGrid filter handling component. The root cause is a failure to enforce 'filterable => false' restrictions on the server side for the 'Tags' column in the Candidates DataGrid. An authenticated attacker can manipulate filter requests to target this non-filterable column, bypassing intended restrictions to inject malicious SQL syntax. This allows for unauthorized data extraction or modification. While a patch has been described (skipping server-side processing for non-filterable columns), a specific patched version number was not confirmed in the advisory text.
