To mitigate CVE-2026-3616, organizations should immediately apply the official patch (commit f0e991870e9d33701cca3a1d0fd4eec135af01a6) provided by DefaultFuction for Jeson CRM version 1.0.0. Beyond patching, it is critical to implement input validation and parameterized queries or prepared statements to prevent SQL injection. Conduct a thorough code review of all modules handling user input, especially those interacting with databases. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the 'ID' parameter or similar inputs. Monitor logs for unusual database queries or errors indicative of injection attempts. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. Regularly back up CRM data and test restoration procedures to ensure resilience against data corruption or loss. Finally, educate developers and administrators on secure coding practices and vulnerability management to prevent recurrence.
