CVE-2023-35934 – yt-dlp File Downloader cookie leak

https://notcve.org/view.php?id=CVE-2023-35934

yt-dlp is a command-line program to download videos from video sites. During file downloads, yt-dlp or the external downloaders that yt-dlp employs may leak cookies on HTTP redirects to a different host, or leak them when the host for download fragments differs from their parent manifest's host. This vulnerable behavior is present in yt-dlp prior to 2023.07.06 and nightly 2023.07.06.185519. All native and external downloaders are affected, except for `curl` and `httpie` (version 3.1.0 or later). At the file download stage, all cookies are passed by yt-dlp to the file downloader as a `Cookie` header, thereby losing their scope. This also occurs in yt-dlp's info JSON output, which may be used by external tools. • https://github.com/yt-dlp/yt-dlp-nightly-builds/releases/tag/2023.07.06.185519 https://github.com/yt-dlp/yt-dlp/commit/1ceb657bdd254ad961489e5060f2ccc7d556b729 https://github.com/yt-dlp/yt-dlp/commit/3121512228487c9c690d3d39bfd2579addf96e07 https://github.com/yt-dlp/yt-dlp/commit/f8b4bcc0a791274223723488bfbfc23ea3276641 https://github.com/yt-dlp/yt-dlp/releases/tag/2023.07.06 https://github.com/yt-dlp/yt-dlp/security/advisories/GHSA-v8mc-9377-rwjj https://lists.fedoraproject.org/archives/list/package • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
