CVE-2026-45288: Jasperfx Marten

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Jasperfx Marten: before 8.36.1 (fixed in 8.36.1)
