What is CVE-2026-54455?

OpenCATS, an open-source applicant tracking system used by staffing agencies, is affected by a SQL injection vulnerability due to improper validation of user input in the DataGrid date filtering mechanism. Specifically, the startDate, endDate, and period parameters are directly inserted into SQL queries without adequate sanitization. This allows an authenticated user to manipulate SQL queries to expose sensitive database information, including user accounts, candidate data, and activity histories. The issue has been resolved in version 0.10.0, emphasizing the importance of updating to the latest software release to mitigate risks.

Affected Version(s)
