As a result, some very uncommon extensions might not get downloaded.\n\n### Workarounds\nAny/all of the below considerations may limit exposure in case it is necessary to use a vulnerable version\n* have `.%(ext)s` at the end of the output template\n* download from websites that you trust\n* do not download to a directory within the executable search `PATH` or other sensitive locations, such as your user directory or system directories\n* in Windows versions that support it, set [`NoDefaultCurrentDirectoryInExePath`](https://stackoverflow.com/a/50118548) to prevent the _cmd_ shell's executable search adding the default directory before `PATH`\n* consider that the path traversal vulnerability as a result of resolving `non_existent_dir\\..\\..\\target` does not exist in Linux or macOS\n* ensure the extension of the media to download is a common video/audio/... one (use `--get-filename`)\n* omit any of the subtitle options (`--write-subs`/` --write-srt`, `--write-auto-subs`/`--write-automatic-subs`, `--all-subs`).\n\n### References\n* [GHSA-79w7-vh3h-8g4j](https://github.com/yt-dlp/yt-dlp/security/advisories/GHSA-79w7-vh3h-8g4j)\n* https://github.com/ytdl-org/youtube-dl/pull/32830", + "severity": [ + { + "type": "CVSS_V3", + "score": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H" + } + ], + "affected": [ + { + "package": { + "ecosystem": "PyPI", + "name": "youtube-dl" + }, + "ranges": [ + { + "type": "ECOSYSTEM", + "events": [ + { + "introduced": "2015.01.25" + }, + { + "fixed": "2024-07-03" + } + ] + } + ], + "database_specific": { + "last_known_affected_version_range": "<= 2021.12.17" + } + } + ], + "references": [ + { + "type": "WEB", + "url": "https://github.com/dirkf/youtube-dl/security/advisories/GHSA-22fp-mf44-f2mq" + }, + { + "type": "WEB", + "url": "https://github.com/yt-dlp/yt-dlp/security/advisories/GHSA-79w7-vh3h-8g4j" + }, + { + "type": "ADVISORY", + "url": "https://nvd.nist.gov/vuln/detail/CVE-2024-38519" + }, + { + "type": "WEB", + "url": "https://github.com/ytdl-org/youtube-dl/pull/32830" + }, + { + "type": "WEB", + "url": "https://github.com/ytdl-org/youtube-dl/commit/d42a222ed541b96649396ef00e19552aef0f09ec" + }, + { + "type": "PACKAGE", + "url": "https://github.com/dirkf/youtube-dl" + }, + { + "type": "ADVISORY", + "url": "https://securitylab.github.com/advisories/GHSL-2024-089_youtube-dl" + } + ], + "database_specific": { + "cwe_ids": [ + "CWE-434", + "CWE-669" + ], + "severity": "HIGH", + "github_reviewed": true, + "github_reviewed_at": "2025-04-18T20:24:07Z", + "nvd_published_at": null + } +} \ No newline at end of file
