Recurring patterns

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

Auth Bypass: Inadequate verification of the digest algorithm size allows the use of weak hashes like MD5. This causes RFC 4226 dynamic truncation to execute out-of-bounds, resulting in predictable OTPs that bypass authentication entirely.

Mass Assignment: Unsanitized query parameters parsed from provisioning URIs are dynamically assigned to internal object properties. Attackers can leverage this to overwrite critical internal state, flags, or clock parameters.
