Description

TinyIce is a streaming server for audio and video. In versions 0.8.95 through 2.4.1, missing authentication on WebRTC ingest endpoint allows unauthenticated stream injection. Version 2.5.0 fixes the issue by requiring either HTTP Basic auth or a `?password=` query parameter, comparing the supplied password against the per-mount source password (or the `default_source_password` fallback) using bcrypt, hooking into the existing brute-force IP rate-limiter (5 failed attempts per IP within 15 minutes triggers a lockout), and rejecting requests for mounts in `disabled_mounts`. The same release also tightens an adjacent endpoint, `POST /admin/golive/chunk`, which previously required session authentication but did not verify the session user's per-mount access nor check the CSRF token.
