Upstream source description

AzuraCast before 0.24.0 contains a server-side request forgery vulnerability that allows station users with WebHooks permission to bypass the UserUrlFilter guard via the Mastodon, Telegram, GroupMe, and RadioReg connectors. Attackers can set instance_url, api, or webhookurl to internal addresses and trigger the webhook test endpoint to reach loopback, private-network, or cloud-metadata services.
