CVE-2026-62361: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in knadh listmonk
A SQL injection vulnerability exists in listmonk prior to version 6.2.0 in the GET /api/subscribers/export endpoint. This endpoint improperly injects a user-controlled query parameter into an internal function without proper validation, allowing an authenticated user with specific privileges to read arbitrary database tables and execute data-modifying PostgreSQL common table expressions (CTEs). The issue is fixed in version 6.2.0.
AI Analysis
Technical Summary
listmonk versions before 6.2.0 have a SQL injection vulnerability (CWE-89) in the GET /api/subscribers/export API endpoint. Unlike the GET /api/subscribers endpoint, this export endpoint fails to call the validateQueryTables function before passing a user-controlled query parameter into QuerySubscribersForExport in internal/core/subscribers.go. This flaw allows an authenticated user with subscribers:sql_query and subscribers:get_all permissions to access arbitrary database tables such as users and settings and to execute data-modifying PostgreSQL CTEs. The vulnerability is resolved in version 6.2.0.
Potential Impact
An authenticated user with the required permissions can exploit this vulnerability to read sensitive database tables and perform data modifications via PostgreSQL CTEs. This can lead to unauthorized data disclosure and limited data integrity impact. The CVSS score of 5.5 reflects a medium severity with high confidentiality impact and low integrity impact.
Mitigation Recommendations
Upgrade listmonk to version 6.2.0 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are indicated. Patch status is confirmed fixed in 6.2.0.
