CVE-2026-45327

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.

Title

Missing authentication on WebRTC ingest endpoint allows unauthenticated stream injection in TinyIce

Ecosystem / Package

• Ecosystem: Go (or "Other" — TinyIce is shipped as a Go binary, not a Go module published to a registry)
• Package name: github.com/DatanoiseTV/tinyice

Affected versions

>= 0.8.95, <= 2.4.1

(Introduced 2026-02-21 in commit e2b60d6 — "debug: add Go Live connection tracing and backend data flow logging" — when handleWebRTCSourceOffer was registered at /webrtc/source-offer without an authentication check. Every tagged release from v0.8.95 through v2.4.1 ships the vulnerable handler.)

Patched versions

>= 2.5.0

Severity

• CVSS 3.1 base score: 7.4 (High)
• CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L
• CWE: CWE-306: Missing Authentication for Critical Function

Description

TinyIce's WebRTC source-ingest HTTP endpoint, POST /webrtc/source-offer?mount=<mount>, accepted any inbound WebRTC SDP offer with no authentication check. The handler routed the offer to WebRTCManager.HandleSourceOffer, which then accepted whatever audio/video tracks the peer published and broadcast them on the named mount as if they were the legitimate source.

The other ingest paths (POST /<mount> over HTTP/1 with the icecast SOURCE / PUT verb, RTMP, SRT) all require the per-mount source password, falling back to default_source_password from the config. The WebRTC ingest path didn't.

Impact

A network attacker who can reach the TinyIce HTTP port can:

1. Identify a target mount (mount names are public — they appear in the directory listing, the player URL, and the YP listing).
2. Negotiate a WebRTC peer connection with the server.
3. Publish arbitrary Opus / H.264 to that mount.
4. Have it broadcast to every listener on the mount.

This is a high-integrity-impact issue: an attacker can replace a radio's broadcast with their own audio (silence, noise, malicious content, branded competitor content, etc.). Listeners hear what the attacker sends, not what the legitimate publisher intended.

The legitimate publisher can re-establish their session — TinyIce's source-takeover handshake gives the new offer priority once it arrives, with a 3-second drain of the previous pump goroutine — but the attacker can in principle re-connect immediately after, producing a sustained broadcast hijack until the operator manually intervenes (block at firewall, rotate source passwords once the patch is applied, restart the service).

There is no direct confidentiality impact through this endpoint: the attacker doesn't gain access to listener data or other mounts' content.

Workarounds

If users cannot upgrade immediately:

• Recommended: block POST /webrtc/source-offer at the reverse proxy in front of TinyIce. The endpoint has no production use case for clients outside the operator's own administration — disabling it loses no functionality unless the consuming application specifically use the browser-based "go-live" feature.
• Restrict TinyIce's HTTP port to a trusted network (VPN, internal LAN). Listener access can still be served via a separately-firewalled CDN if the application needs public listening.

Detection

To check whether an application's deployment is exposed, run from outside the network:

curl -i -X POST 'https://your-tinyice-host/webrtc/source-offer?mount=/anymount' \
  -H 'Content-Type: application/json' \
  -d '{"type":"offer","sdp":"v=0\r\n"}'

• If the response is 400 Bad Request with a JSON body containing an SDP-parsing error from pion/webrtc, a consuming application is vulnerable — the server tried to negotiate the (malformed) offer without asking for credentials.
• If the response is 401 Unauthorized (Basic auth challenge), the consuming application has been patched.

Authenticated log lines on a patched server will look like:
