Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Certificate Trust Bypass: Compromised TrustCor root CAs were removed, indicating a need to periodically audit and prune untrusted CAs to prevent MITM attacks.
URL Validation Bypass: Unsafe characters (CR, LF, HT) in URLs could bypass validation, leading to request smuggling or SSRF. Early rejection is critical.
Dependency Vulnerability: urllib3 version constraint was too restrictive, missing patched versions for CVE-2019-11236. Keep dependency ranges open to patched releases.
