URL Redirection to Untrusted Site ('Open Redirect')
alltube is an html front end for youtube-dl. CVE-2022-0768 addressed this issue in version 3.0.2 but didn't fix it completely, 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.) Version 3.0.3 contains a fix for this vulnerability.
CWE-601 - Open Redirect
An open redirect attack employs a URL parameter, HTML refresh tags, or a DOM based location change to exploit the trust of a vulnerable domain to direct the users to a malicious website. The attack could lead to higher severity vulnerabilities such as unauthorized access control, account takeover, XSS, and more.
