Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Insecure handling of user-supplied paths and directory names allowed directory traversal, enabling attackers to write arbitrary files to the local file system. This directly resulted in CVE-2025-27519, where attackers could overwrite application files to execute arbitrary code.
SQL Injection: Database operations via the SingleStore Python connector dynamically constructed SQL queries using unvalidated table names, allowing attackers to inject malicious commands directly into cursor executions.
Insecure CORS Configuration: The backend server combined wildcard origins ('*') with allowed credentials inside the CORSMiddleware configuration, violating secure CORS specifications and allowing third-party sites to read sensitive API responses.
