Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Path validation mechanisms in image and file management endpoints historically used insufficient containment checks (such as using os.path.abspath instead of os.path.realpath), allowing attackers to bypass directory restrictions and write or read arbitrary system files.
Cross-Origin Request Forgery: The application lacked host/origin matching controls on highly privileged endpoints, exposing local and remote deployments to CSRF and origin-verification bypasses.
Reflected XSS: Serving stored or uploaded files with executable or renderable MIME types enabled inline execution of arbitrary scripts, bypassing standard containment mechanisms.
