Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Insecure request signing allows parameters containing control characters like ampersands to bypass integrity controls through parameter smuggling, undermining the security of API signatures.
Auth Bypass: Flaws in path canonicalization, URL escaping, and epoch time calculation within token generation logic can generate invalid or overly permissive HMACs, enabling access-control bypasses.
Path Traversal: Inadequate protocol prefix validation in remote resource uploading allows URL handlers to interpret specific schemes as requests for local files, leading to unauthorized local file disclosure.
