Upgrade to JasperFx Marten version 8.36.1 or later, where this SQL injection vulnerability is fixed.

No alternative mitigations are indicated.
Description
CVE-2026-45288 is a critical SQL injection vulnerability in JasperFx Marten versions prior to 8.36.1. The issue arises because the full-text search APIs interpolate the user-supplied regConfig parameter directly into SQL queries without proper parameterization or validation. This allows attackers to inject malicious SQL commands via untrusted input. The vulnerability has a CVSS score of 9.8, indicating high impact on confidentiality, integrity, and availability. A fix is available in version 8.36.1.
