CVE-2026-4776Network attack vector

Database disclosure via nested filter SQL injection

Published May 29, 2026 · Updated May 29, 2026

SQL injection in affected Mautic releases allows remote authenticated users to read database contents through API contact filters. The API contact-filter parser fails to sanitize nested query parameters recursively, so embedded SQL syntax reaches generated database queries. Authenticated API access is required; successful exploitation bypasses ordinary data permissions and exposes credentials, configuration, and contact PII.
