CVE-2026-45288

JasperFx marten

Marten has an SQL injection vulnerability in its full-text search regConfig parameter

CVSS 3.1

9.8Critical

Official description

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.
