SQL injection via unescaped full-text configuration
Published May 28, 2026 · Updated May 28, 2026
SQL injection in JasperFX Software Marten before 8.36.1 allows remote attackers to execute arbitrary PostgreSQL via regConfig. FullTextWhereFragment.Sql places regConfig unchanged inside a single-quoted SQL literal, so a quote terminates the value and appends PostgreSQL. Exploitation requires a calling application to pass attacker-controlled input into regConfig; resulting reads, writes, deletion, or delays are limited by the application database role.
