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-2026-50019 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- yt-dlp (PyPI): affected from 2023.9.24; fixed in 2026.6.9\n- yt-dlp (PyPI): affected from 2023.9.24; fixed in 2026.6.9\n- yt-dlp (PyPI): affected from 2023.9.24; fixed in 2026.6.9\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-2026-50019/ (Markdown: https://insights.sbomify.com/CVE-2026-50019/index.md)","id":"CVE-2026-50019","markdown":"https://insights.sbomify.com/CVE-2026-50019/index.md","name":"CVE-2026-50019","record":{"aliases":["DEBIAN-CVE-2026-50019","GHSA-f7j3-774f-rfhj","PYSEC-2026-3431","UBUNTU-CVE-2026-50019"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"yt-dlp downloader","requires_auth":"none","summary":"Attackers can leak user cookies to unintended hosts when using curl as an external downloader in yt-dlp during redirects or fragment downloads.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"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-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"yt-dlp is a command-line audio/video downloader.

At the file download stage, the cookies are passed by yt-dlp to the file downloader via --cookie. However, unless these are loaded from a file, this operation does not activate the cookie engine. As a result, curl will send cookies with requests to domains or paths for which the cookies are not scoped.
