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 a database query without proper validation, allowing an authenticated user with specific permissions 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 endpoint. The endpoint injects a user-controlled query parameter into the QuerySubscribersForExport function without calling the validateQueryTables function, unlike the GET /api/subscribers endpoint. This allows an authenticated user with subscribers:sql_query and subscribers:get_all permissions to read arbitrary database tables such as users and settings and execute data-modifying PostgreSQL CTEs. The vulnerability is addressed in version 6.2.0.
Potential Impact
An authenticated user with the required permissions can exploit this vulnerability to read sensitive database tables and execute data-modifying SQL commands via PostgreSQL CTEs. This could lead to unauthorized data disclosure and unauthorized modification of database contents. The CVSS v3.1 score is 5.5 (medium severity), reflecting high confidentiality impact, low integrity impact, and no availability 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 documented. Since this is a self-hosted product, users must apply the update themselves to mitigate the issue.
