CVE-2026-33643Public exploitNetwork attack vector

Authenticated database schema tampering via unescaped backticks

Published Mar 30, 2026 · Updated Mar 30, 2026

SQL injection in SchemaHero 0.23.0 allows remote authenticated users to alter MySQL schema queries through a crafted Table CRD. The mysqlColumnAsInsert function in plugins/mysql/lib/column.go wraps column names in backticks without escaping embedded backticks, so a crafted name injects additional column definitions. Automatic execution requires immediateDeploy to be enabled; exploitation also requires permission to create Table CRDs and permits schema tampering.
