CVE-2026-45288 PUBLISHED

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

Assigner: GitHub_M
Reserved: 11.05.2026 Published: 28.05.2026 Updated: 28.05.2026

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.
