Prior to 2026.06.09, a vulnerability exists in yt-dlp that allows a remote attacker to write arbitrary OS-shortcut files (such as .desktop, .url, .webloc) to the user's filesystem, bypassing the remediation for CVE-2024-38519. The allowlist explicitly included the unsafe extensions .desktop, .url, and .webloc so that the functionality of the --write-link option (and its variants) could be preserved. These allowlist inclusions can be exploited by an attacker to write malicious OS-shortcut files in the context of a media or subtitles download. This vulnerability is fixed in 2026.06.09."}], "lastModified": "2026-06-26T20:12:25.540", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:yt-dlp_project:yt-dlp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A130AEBA-F516-4138-9BD8-8D2676A468F6", "versionEndExcluding": "2026.06.09"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
