CVE-2026-45288 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
