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-2022-21806 exists.\n\nAffected product: Anker Eufy Homebase 2. 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-2022-21806/ (Markdown: https://insights.sbomify.com/CVE-2022-21806/index.md)","id":"CVE-2022-21806","markdown":"https://insights.sbomify.com/CVE-2022-21806/index.md","name":"CVE-2022-21806","record":{"aliases":["GHSA-3vc5-mpf6-vw2r"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Smart home hub","requires_auth":"none","summary":"Remote attackers can achieve code execution on Anker Eufy Homebase 2 devices via crafted network packets exploiting a use-after-free flaw.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"eufy_homebase_2_firmware","vendor":"anker"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-368","name":"Context Switching Race Condition"}],"description":"A use-after-free vulnerability exists in the mips_collector appsrv_server functionality of Anker Eufy Homebase 2 2.1.8.5h.
