What is CVE-2026-49490?

OpenCATS version 0.9.1a is susceptible to an SQL injection vulnerability located within the DataGrid filter handling mechanism. This flaw permits authenticated users to inject malicious SQL commands by crafting specific filters aimed at the non-filterable Tags column within the Candidates DataGrid. By manipulating the filter requests, attackers can effectively bypass restrictions intended to secure the database, enabling them to execute arbitrary SQL queries, potentially compromising sensitive data.
