An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-35934 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- yt-dlp (PyPI): affected all versions; fixed in 2023.7.06\n- yt-dlp (PyPI): affected all versions; fixed in 2023.7.06\n- yt-dlp (PyPI): affected all versions; fixed in 2023.7.06\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-35934/ (Markdown: https://insights.sbomify.com/CVE-2023-35934/index.md)","id":"CVE-2023-35934","markdown":"https://insights.sbomify.com/CVE-2023-35934/index.md","name":"CVE-2023-35934","record":{"aliases":["DEBIAN-CVE-2023-35934","GHSA-v8mc-9377-rwjj","PYSEC-2026-2067","UBUNTU-CVE-2023-35934","openSUSE-SU-2024:13142-1"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Video downloader tool","requires_auth":"none","summary":"Attackers can steal session cookies via HTTP redirects or fragmented downloads, potentially leading to account takeover.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"youtube-dlc","vendor":"youtube-dlc_project"},{"product":"youtube-dl","vendor":"yt-dl"},{"product":"yt-dlp","vendor":"yt-dlp_project"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"yt-dlp is a command-line program to download videos from video sites. During file downloads, yt-dlp or the external downloaders that yt-dlp employs may leak cookies on HTTP redirects to a different host, or leak them when the host for download fragments differs from their parent manifest's host. This vulnerable behavior is present in yt-dlp prior to 2023.07.06 and nightly 2023.07.06.185519. All native and external downloaders are affected, except for `curl` and `httpie` (version 3.1.0 or later).\n\nAt the file download stage, all cookies are passed by yt-dlp to the file downloader as a `Cookie` header, thereby losing their scope. This also occurs in yt-dlp's info JSON output, which may be used by external tools. As a result, the downloader or external tool may indiscriminately send cookies with requests to domains or paths for which the cookies are not scoped.\n\nyt-dlp version 2023.07.06 and nightly 2023.07.06.185519 fix this issue by removing the `Cookie` header upon HTTP redirects; having native downloaders calculate the `Cookie` header from the cookiejar, utilizing external downloaders' built-in support for cookies instead of passing them as header arguments, disabling HTTP redirectiong if the external downloader does not have proper cookie support, processing cookies passed as HTTP headers to limit their scope, and having a separate field for cookies in the info dict storing more information about scoping\n\nSome workarounds are available for those who are unable to upgrade. Avoid using cookies and user authentication methods. While extractors may set custom cookies, these usually do not contain sensitive information. Alternatively, avoid using `--load-info-json`. Or, if authentication is a must: verify the integrity of download links from unknown sources in browser (including redirects) before passing them to yt-dlp; use `curl` as external downloader, since it is not impacted; and/or avoid fragmented formats such as HLS/m3u8, DASH/mpd and ISM.","ecosystems":["PyPI","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"yt-dlp File Downloader cookie leak","id":"CVE-2023-35934","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"information_disclosure","year":"2023"},"n_packages":4,"n_references":10,"next":{"headline":"Arbitrary file write is possible in Pandoc when using PDF output or --extract-media with untrusted input","id":"CVE-2023-35936"},"packages":[{"ecosystem":"PyPI","fixed":["2023.7.06"],"introduced":["0"],"last_affected":[],"package":"yt-dlp","purl":null,"source":"GHSA-v8mc-9377-rwjj"},{"ecosystem":"PyPI","fixed":["2023.7.06"],"introduced":["0"],"last_affected":[],"package":"yt-dlp","purl":"pkg:pypi/yt-dlp","source":"GHSA-v8mc-9377-rwjj"},{"ecosystem":"PyPI","fixed":["2023.7.06"],"introduced":["0"],"last_affected":[],"package":"yt-dlp","purl":"pkg:pypi/yt-dlp","source":"PYSEC-2026-2067"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["2023.07.06-1.1"],"introduced":["0"],"last_affected":[],"package":"yt-dlp","purl":"pkg:rpm/opensuse/yt-dlp\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:13142-1"}],"prev":{"headline":"OpenFGA denial of service die to circular relationship","id":"CVE-2023-35933"},"products":["yt-dlp"],"published":"2023-07-06","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["yt-dlp"]},"summary":"Attackers can steal session cookies via HTTP redirects or fragmented downloads, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2023-35934/"}
