## Summary

OpenCATS, an open-source applicant tracking and recruitment CRM used by staffing agencies and hiring teams, is affected before version 0.10.0 through flaws in the activity and calls DataGrid date filters. An logged-in user can manipulate those filter inputs to run unintended database queries, potentially exposing sensitive data such as user accounts, candidate and contact details, company information, job orders, and activity history.

## Affected

- OpenCATS: fixed in 0.10.0

## Description

OpenCATS is an open-source applicant tracking system and recruitment CRM for staffing agencies and hiring teams. Prior to version 0.10.0, activity DataGrid date filtering in `home:CallsDataGrid` and `activity:ActivityDataGrid` uses request-controlled `period`, `startDate` and `endDate` parameters without sufficient validation or escaping. The vulnerable code is in `modules/home/dataGrids.php` and `modules/activity/dataGrids.php`. The `startDate` and `endDate` values are inserted into SQL string comparisons without safe escaping, and `period` can directly influence generated SQL. An authenticated user with access to the affected DataGrid endpoints can alter the intended query to access sensitive database contents, including user account data, candidate records, contact details, company information, job orders and activity history. A valid OpenCATS login is required; unauthenticated exploitation is not established. This issue is fixed in version 0.10.0.
