Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Attackers can bypass path sanitization via newline characters or directory traversal sequences to write arbitrary files. Normalization must be rigidly applied prior to file operations.
Auth Bypass: Sensitive routes, including private verification endpoints and CREATE2 sessions, have historically lacked token authorization or validation rules, exposing privileged capabilities.
Denial of Service: Uncaught verification task rejections and improper active-job tracking can lead to worker pool exhaustion or allow duplicate expensive verification requests.
