CVE-2026-124442: AzuraCast server-side request forgery via webhook redirects

CVE-2026-124442 · Severity: medium · CVSS 6.5 · Published 2026-11-08

AzuraCast is an open-source web radio platform that allows users to configure webhooks to external services like Mastodon and Telegram. A user with webhook permissions can bypass the server's security filter by using HTTP redirects to make the server request internal services, potentially exposing sensitive metadata or credentials. This could allow an attacker to read internal data or interact with restricted systems without direct access.

Technical details

The UserUrlFilter validates the initial user-supplied URL's host to prevent SSRF attacks, but the Guzzle HTTP client follows 3xx redirects by default without re-validating the target. Users with station WebHooks permission can configure Mastodon, Telegram, GroupMe, or RadioReg webhooks pointing to an open redirector, causing the server to follow redirects to internal addresses (127.0.0.1, 169.254.169.254, etc.) that bypass the filter. Internal response bodies are logged and can be read via the test-log endpoint.
