The vulnerability with the CVE ID CVE-2023-35934 affects yt-dlp, a command-line program used for downloading videos from video sites. It is present in versions prior to 2023.07.06 and nightly 2023.07.06.185519. This vulnerability allows cookies to be leaked during file downloads on HTTP redirects to a different host or when the host for download fragments differs from their parent manifest's host. All native and external downloaders are affected except for 'curl' and 'httpie' (version 3.1.0 or later). The cookies are passed as a 'Cookie' header at the file download stage, losing their scope and causing potential indiscriminate sending of cookies with requests to domains or paths for which they are not scoped. The issue is fixed in yt-dlp versions 2023.07.06 and nightly 2023.07.06.185519 by removing the 'Cookie' header upon HTTP redirects. This vulnerability poses a potential danger to organizations as it can lead to information exposure and compromise the confidentiality of sensitive data.
