Impact

Releases prior to 3.0.2 are vulnerable to a Server-Side Request Forgery vulnerability that allows an attacker to send a request to an internal hostname.

Patches

3.0.2 contains a fix for this vulnerability.
(The 1.x and 2.x releases are not maintained anymore.)

Part of the fix requires applying a patch to youtube-dl to prevent it from following HTTP redirects. If you are using the version of youtube-dl bundled with 3.0.2, it is already patched.
However, if you are using your own unpatched version of youtube-dl you might still be vulnerable.
