AI-suggested

European organizations should immediately verify their Listmonk version and upgrade to version 5.0.0 or later, where this vulnerability is fixed. If upgrading is not immediately feasible, implement strict input validation and parameterized queries in the QuerySubscribers function to prevent SQL Injection. Employ Web Application Firewalls (WAFs) with rules targeting SQL Injection patterns specific to Listmonk queries. Conduct thorough code reviews and penetration testing focusing on database query functions. Monitor logs for unusual query patterns or access attempts to subscriber data. Additionally, restrict database user permissions to the minimum necessary to limit the impact of any injection attempts. Regularly update and patch Listmonk installations and maintain an inventory of affected systems to ensure timely remediation.

Description

Listmonk v4.1.0 (fixed in v5.0.0) is vulnerable to SQL Injection in the QuerySubscribers function which allows attackers to escalate privileges.
