CVE-2026-45288

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.

Summary		(es) Marten es una base de datos de documentos transaccional .NET y almacén de eventos sobre PostgreSQL. Antes de la versión 8.36.1, las API de búsqueda de texto completo de Marten interpolaban el parámetro regConfig suministrado por el usuario directamente en el SQL generado sin parametrización ni validación, convirtiendo cada ruta de código que expone regConfig a entrada no confiable en un sumidero de inyección SQL. Esta vulnerabilidad está corregida en la versión 8.36.1.
