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.
Summary dbcve.org
Krayin CRM before 2.2.4 contains a blind SQL injection in the leads DataGrid where the 'rotten_lead[in]' query parameter is concatenated directly into a havingRaw() call in LeadDataGrid.php without parameterized binding, allowing authenticated attackers to inject arbitrary SQL into the HAVING clause.
Mitigation
Upgrade to Krayin CRM 2.2.4 or later which implements proper parameterized binding for the havingRaw() call. If immediate upgrade is not possible, implement input validation/sanitization on the rotten_lead[in] parameter.
