Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to the latest version of Fluent Forms (beyond 4.3.25) which contains the patched code. If patching is not immediately possible, consider disabling the plugin until updated. The fix requires implementing parameterized queries (prepared statements) for all database interactions that accept user input.
