{"id":"ALPINE-CVE-2024-38519","details":"`yt-dlp` and `youtube-dl` are command-line audio/video downloaders. Prior to the fixed versions, `yt-dlp` and `youtube-dl` do not limit the extensions of downloaded files, which could lead to arbitrary filenames being created in the download folder (and path traversal on Windows). Since `yt-dlp` and `youtube-dl` also read config from the working directory (and on Windows executables will be executed from the `yt-dlp` or `youtube-dl` directory), this could lead to arbitrary code being executed.\n\n\n\n\n`yt-dlp` version 2024.07.01 fixes this issue by whitelisting the allowed extensions. `youtube-dl` fixes this issue in commit `d42a222` on the `master` branch and in nightly builds tagged 2024-07-03 or later. This might mean some very uncommon extensions might not get downloaded, however it will also limit the possible exploitation surface. In addition to upgrading, have `.%(ext)s` at the end of the output template and make sure the user trusts the websites that they are downloading from. Also, make sure to never download to a directory within PATH or other sensitive locations like one's user directory, `system32`, or other binaries locations. For users who are not able to upgrade, keep the default output template (`-o \"%(title)s [%(id)s].%(ext)s`); make sure the extension of the media to download is a common video/audio/sub/... one; try to avoid the generic extractor; and/or use `--ignore-config --config-location ...` to not load config from common locations.","modified":"2026-10-27T08:33:31.654989162Z","published":"2024-07-02T14:15:13.737Z","upstream":["CVE-2024-38519"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-38519"}],"affected":[{"package":{"name":"yt-dlp","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/yt-dlp?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2024.07.01-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2024-38519.json"}},{"package":{"name":"yt-dlp","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/yt-dlp?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2024.07.01-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2024-38519.json"}},{"package":{"name":"yt-dlp","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/yt-dlp?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2024.07.01-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2024-38519.json"}},{"package":{"name":"yt-dlp","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/yt-dlp?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2024.07.01-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2024-38519.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
