What is CVE-2026-41453?

Krayin CRM versions prior to 2.2.4 are susceptible to a blind SQL injection vulnerability found in the leads DataGrid. This issue arises when authenticated users manipulate the 'rotten_lead[in]' query parameter, allowing them to inject arbitrary SQL into a HAVING clause. The vulnerability stems from the lack of parameterized SQL statements, which results in user input being directly concatenated into a havingRaw() call within LeadDataGrid.php. Exploitation of this vulnerability can enable attackers to execute time-based and boolean-based blind injection techniques, facilitating the extraction of sensitive data including user credential hashes, CRM records, and app configuration data.
