CVE-2023-46121

yt-dlp is a youtube-dl fork with additional features and fixes. The Generic
Extractor in yt-dlp is vulnerable to an attacker setting an arbitrary proxy
for a request to an arbitrary url, allowing the attacker to MITM the
request made from yt-dlp’s HTTP session. This could lead to cookie
exfiltration in some cases. Version 2023.11.14 removed the ability to
smuggle http_headers to the Generic extractor, as well as other
extractors that use the same pattern. Users are advised to upgrade. Users
unable to upgrade should disable the Ggneric extractor (or only pass
trusted sites with trusted content) and ake caution when using
--no-check-certificate.
