It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47739 exists.\n\nAffected product: Epic Games Easy Anti-Cheat. 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-2021-47739/ (Markdown: https://insights.sbomify.com/CVE-2021-47739/index.md)","id":"CVE-2021-47739","markdown":"https://insights.sbomify.com/CVE-2021-47739/index.md","name":"CVE-2021-47739","record":{"aliases":["GHSA-r6ff-6pwf-xvp7"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Anti-Cheat Software","requires_auth":"low_privilege","summary":"Local attackers can execute arbitrary code with system privileges by exploiting an unquoted service path in Epic Games Easy Anti-Cheat.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-428","name":"Unquoted Search Path or Element"}],"description":"Epic Games Easy Anti-Cheat 4.0 contains an unquoted service path vulnerability that allows local non-privileged users to execute arbitrary code with elevated system privileges.
