Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

SSRF: Most frequently fixed class with 5 patches, each closing a distinct bypass (IPv6 transition, loopback, connect-time rebinding, fail-closed, ingress validation). The sink is the yt-dlp generic extractor and socket.getaddrinfo, making it the highest-risk surface for internal network access.

Path Traversal: Three fixes spanning input validation (custom_name_prefix, chapter_template) and resolved-path containment (_ConfinedYoutubeDL). The critical fix at prepare_filename is the chokepoint, but sibling paths like playlist/channel title handling remain risk.

CORS Misconfiguration: Two fixes replaced wildcard origin reflection and Socket.IO wildcard with explicit allowlists. Credentialed requests with wildcard origin are a classic high-severity issue; the allowlist must be maintained as the default-deny posture.
