GHSA-c6mh-fpjc-4pr3: yt-dlp (CVE-2026-50023)

Package	Ecosystem	Affected	Fixed in
yt-dlp	PyPI	<2026.6.9	2026.6.9

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

yt-dlp versions before 2026.6.9 are vulnerable. A remote attacker who can get a user to download media from a crafted playlist or manifest can cause yt-dlp to write attacker-controlled OS-shortcut files such as .desktop, .url or .webloc next to the downloaded media, which can lead to phishing or arbitrary code execution if the user opens the file. Upgrade to yt-dlp 2026.6.9. Users who cannot upgrade should only pass trusted URLs and avoid the subtitle and thumbnail write options.
