SQL Injection in Marten (CVE-2026-45288)
Summary
SQL injection in Marten (CVE-2026-45288). Successful exploitation can lead to full system takeover. Exploitable via regConfig. Mitigation: upgrade to 8.37.0 or later.
Original description
The description as published by the source.
Marten is a .NET Transactional Document DB and Event Store on PostgreSQL. Prior to 8.36.1, Marten's full-text search APIs interpolated the user-supplied regConfig parameter directly into the generated SQL without parameterization or validation, making every code path that exposes regConfig to untrusted input a SQL injection sink. This vulnerability is fixed in 8.36.1.
