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-2026-12223 exists.\n\nAffected product: Yealink SIP-T46U. 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-2026-12223/ (Markdown: https://insights.sbomify.com/CVE-2026-12223/index.md)","id":"CVE-2026-12223","markdown":"https://insights.sbomify.com/CVE-2026-12223/index.md","name":"CVE-2026-12223","record":{"aliases":["GHSA-pcph-rxv7-4pvp"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"VoIP phone","requires_auth":"low_privilege","summary":"A command injection vulnerability in the Yealink SIP-T46U web service allows local network attackers to execute arbitrary commands via the TFTP upload interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"A vulnerability was identified in Yealink SIP-T46U 108.86.0.118. Affected by this vulnerability is the function mod_webd.TFTPUploadIperf of the file /api/inner/tftpuploadiperf of the component Web FastCGI Service. The manipulation of the argument ip/port leads to command injection. The attack needs to be initiated within the local network. The exploit is publicly available and might be used. Upgrading to version 108.87.0.23 addresses this issue. Upgrading the affected component is recommended. The vendor explains: \"It has been fixed (...) for our technical support branch.
