Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: The backend allowed arbitrary file reads and directory traversal due to insufficient validation of user-controlled paths prior to file system operations. Proper path normalization and anchor-prefix checks are necessary to prevent sensitive system files from leaking.
Auth Bypass: Lack of flow ownership and permission validation enabled unauthorized API requests to associate assistants with workflows belonging to other users, leading to privilege escalation and data manipulation.
SQL Injection: Direct interpolation of user inputs using formatted strings (fmt.Sprintf) inside SQL queries allowed remote attackers to execute arbitrary database queries. Parameterization of all database access layers is critical to prevent complete database compromise.
