CVE-2026-41453

Description

Krayin CRM before 2.2.4 contains a blind SQL injection vulnerability in the leads DataGrid that allows authenticated users with leads access to inject arbitrary SQL into a HAVING clause by manipulating the rotten_lead[in] query parameter, which is concatenated without parameterized binding directly into a havingRaw() call in LeadDataGrid.php. Attackers can exploit this flaw using time-based and boolean-based blind injection techniques to extract the entire database contents, including user credential hashes, CRM records, and application configuration data.
