CVE-2026-6093Public exploitNetwork attack vector

Authenticated SQL injection via incorrect T-SQL escaping

Published May 11, 2026 · Updated May 11, 2026

SQL injection in Corteza 2024.9.8 allows remote authenticated users to read or alter database data through a crafted Compose meta filter. The MSSQL jsonPath function backslash-escapes quotes in attacker-controlled JSON keys even though T-SQL requires quote doubling, while ParseMeta skips key validation for JSON objects. Exploitation requires an MSSQL-backed deployment, records.search permission on a module, and at least one record; the demonstrated blind oracle reads database values.
