What is CVE-2024-22423?

The yt-dlp project, a popular fork of youtube-dl, has a vulnerability that can lead to remote code execution due to improper handling of input within the '--exec' command. This issue arises from an insufficient escaping mechanism introduced in a previous patch, which was intended to mitigate risks associated with code execution through unvalidated command template expansions. In version 2021.04.11, the escaping of double quotes was deemed inadequate, still allowing for the execution of arbitrary commands through environment variable expansion. The vulnerability has been addressed in version 2024.04.09, where a more secure escaping method replaces vulnerable patterns. Users are strongly advised to upgrade to the latest version immediately and exercise caution when utilizing the '--exec' feature, especially with untrusted input.
