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: There is no known exploitation of CVE-2026-34223 in the wild and no public exploit code.\n\nAffected product: Siemens Desigo CC ClickOnce Client V6. 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-2026-34223/ (Markdown: https://insights.sbomify.com/CVE-2026-34223/index.md)","id":"CVE-2026-34223","markdown":"https://insights.sbomify.com/CVE-2026-34223/index.md","name":"CVE-2026-34223","record":{"aliases":["GHSA-3r86-r8f3-cmm5"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens Desigo CC client","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code and write files on client systems by tricking users into opening malicious graphics documents in Siemens Desigo CC clients.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A vulnerability has been identified in Desigo CC ClickOnce Client V6 (All versions), Desigo CC ClickOnce Client V7 (All versions), Desigo CC family V8 (All versions), Desigo CC family V9 (All versions), Desigo CC Flex Client V6 (All versions), Desigo CC Flex Client V7 (All versions), Desigo CC Installed Client V6 (All versions), Desigo CC Installed Client V7 (All versions). The affected application is vulnerable to Client Code Execution (CCE) due to insufficient input validation when handling scripts embedded within user-defined graphics documents.  Specifically, when the script within a graphics document is designed or modified by an attacker to include malicious commands.  When a user opens a compromised graphics document, the embedded script is executed on the client application instance, allowing an attacker to write arbitrary files to the client's operating system. Successful exploitation requires an attacker to craft a malicious graphics document and entice a user with sufficient privileges to display it.  This could lead to compromise of the client operating system and potential lateral movement within the organization.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Code injection in Desigo CC ClickOnce Client V6","id":"CVE-2026-34223","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Parse Server: MFA single-use token bypass via concurrent authData login requests","id":"CVE-2026-34224"},"packages":[],"prev":{"headline":"Open WebUI has Broken Access Control in Tool Valves","id":"CVE-2026-34222"},"products":["Desigo CC ClickOnce Client V6","Desigo CC ClickOnce Client V7","Desigo CC Flex Client V6","Desigo CC Flex Client V7","Desigo CC Installed Client V6","Desigo CC Installed Client V7","Desigo CC family V8","Desigo CC family V9"],"published":"2026-09-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["Siemens"]},"summary":"Attackers can execute arbitrary code and write files on client systems by tricking users into opening malicious graphics documents in Siemens Desigo CC clients.","url":"https://insights.sbomify.com/CVE-2026-34223/"}
