CVE-2026-54455 · Severity: high · CVSS 7.6 · Published 2026-10-28

OpenCATS is an open-source applicant tracking system used by staffing agencies and hiring teams to manage candidates and job orders. A flaw in the date filtering feature allows authenticated users to inject SQL commands that expose sensitive database contents, including candidate records, user accounts, contact details, and job information. While a valid login is required, this enables insiders or compromised accounts to steal confidential recruitment data.

## How to fix

- Fixed in 0.10.0

Restrict access to the affected DataGrid views (home:CallsDataGrid and activity:ActivityDataGrid) to trusted users only until upgrading. This reduces exposure for authenticated users but does not eliminate the vulnerability.

## Technical details

Authenticated SQL injection vulnerability in the `home:CallsDataGrid` and `activity:ActivityDataGrid` components caused by insufficient validation and escaping of the `period`, `startDate`, and `endDate` request parameters in `modules/home/dataGrids.php` and `modules/activity/dataGrids.php`. An authenticated user can craft malicious date filter input to alter the SQL query and access sensitive database records. The vulnerability requires a valid OpenCATS login but no further user interaction.

## Affected products

- OpenCATS OpenCATS prior to 0.10.0
