Server side request forgery (ssrf)

alltube is an html front end for youtube-dl. On releases prior to 3.0.3, an attacker could craft a special HTML page to trigger either an open redirect attack or a Server-Side Request Forgery attack (depending on how AllTube is configured). The impact is mitigated by the fact the SSRF attack is only possible when the stream option is enabled in the configuration. (This option is disabled by default.) 3.0.3 contains a fix for this vulnerability.
