It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47775 exists.\n\nAffected product: Litexmedia YouTube Video Grabber. 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-2021-47775/ (Markdown: https://insights.sbomify.com/CVE-2021-47775/index.md)","id":"CVE-2021-47775","markdown":"https://insights.sbomify.com/CVE-2021-47775/index.md","name":"CVE-2021-47775","record":{"aliases":["GHSA-43mg-fm9r-vj2p"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"YouTube Video Grabber","requires_auth":"none","summary":"Attackers can execute arbitrary code via a buffer overflow in YouTube Video Grabber by overwriting the Structured Exception Handler with a malicious payload.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"YouTube Video Grabber, now referred to as YouTube Downloader, 1.9.9.1 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting the Structured Exception Handler.
