An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-109967 exists.\n\nAffected product: marcopiovanello yt-dlp-web-ui. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-109967/ (Markdown: https://insights.sbomify.com/CVE-2026-109967/index.md)","id":"CVE-2026-109967","markdown":"https://insights.sbomify.com/CVE-2026-109967/index.md","name":"CVE-2026-109967","record":{"aliases":["GHSA-vw64-j3q3-fxf9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"yt-dlp web UI","requires_auth":"none","summary":"Remote unauthenticated attackers can crash the yt-dlp-web-ui server by sending a crafted request to the Service.Formats method.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"yt-dlp-web-ui through 4.0.0 contains a NULL pointer dereference vulnerability in the Service.Formats JSON-RPC method that allows remote unauthenticated attackers to crash the server.
