The vulnerable behavior is present in yt-dlp released since 2023.09.24.\n\n### Details\nAt the file download stage, the cookies are passed by yt-dlp to the file downloader via `--cookie`. However, unless these are loaded from a file, this operation does not activate the cookie engine. As a result, `curl` will send cookies with requests to domains or paths for which the cookies are not scoped.\n\nAn example of a potential attack scenario exploiting this vulnerability:\n1. an attacker has crafted a malicious website with an embedded URL designed to be detected by yt-dlp as a video download. This embedded URL has the domain of a trusted site that the user has loaded cookies for, and conducts an [unvalidated redirect](https://cheatsheetseries.owasp.org/cheatsheets/Unvalidated_Redirects_and_Forwards_Cheat_Sh","public_affected_ranges":[">= 2023.9.24, < 2026.6.9"]}],"null_published_at":"2026-11-04T10:04:27.944Z","source_updated_at":"2026-07-20T13:45:42.000Z","source_disclosed_at":"2026-06-16T20:16:56.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-04T02:49:06.528Z"}],"next_cursor":null,"snapshot_revision":"42594"}
