Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incomplete signature verification in callback handling could allow unauthorized requests to bypass authentication. This was mitigated by updating validation to robustly handle both old Qbox and modern Qiniu signature schemes.
Insecure Temporary File: Using predictable shared system temporary files for caching regions allowed local privilege escalation or cache poisoning. This was addressed by ensuring cache files are isolated inside a dedicated, securely created subdirectory.
