Highlights

Denial of Service: 2 prior fixes. Scrutinize any change in this area.

1 high-severity fix in this history; regressions here are high-impact.

Recurring patterns

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

Denial of Service: Unbounded message buffering during frame assembly could exhaust memory; fixed by emitting partial frames.

Cryptographic Weakness: Masking key generation used a weak PRNG, allowing prediction; replaced with os.urandom.

Auth Bypass: Handshake without Host header could bypass host-based security; now explicitly required.
