An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21662 in the wild and no public exploit code.\n\nAffected product: Johnson Controls FM Systems Employee. 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-2026-21662/ (Markdown: https://insights.sbomify.com/CVE-2026-21662/index.md)","id":"CVE-2026-21662","markdown":"https://insights.sbomify.com/CVE-2026-21662/index.md","name":"CVE-2026-21662","record":{"aliases":["GHSA-9m8h-rcg4-v896"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FM Systems Employee","requires_auth":"high_privilege","summary":"Attackers can upload malicious files to Johnson Controls FM Systems Employee, potentially leading to code execution.","user_interaction":"required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[{"product":"fms_employee","vendor":"johnsoncontrols"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted upload of file with dangerous type vulnerability in Johnson Controls FM Systems Employee allows Using Malicious Files.\n\nThis issue affects FM Systems Employee: before 2025.3.1.","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":"FMS Employee Allows Upload of Unrestricted Files","id":"CVE-2026-21662","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Revive Adserver","id":"CVE-2026-21663"},"packages":[],"prev":{"headline":"AC2000 Uncontrolled Search Path Element","id":"CVE-2026-21661"},"products":["FM Systems Employee"],"published":"2026-07-31","related":[{"cvss_score":4.8,"headline":"FMS Employee vulnerable to XSS","id":"CVE-2026-34495","kev_date_added":null,"published":"2026-07-31"},{"cvss_score":4.8,"headline":"FMS Employee Vulnerable to HTML Injection","id":"CVE-2026-34497","kev_date_added":null,"published":"2026-07-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-07-31","vendors":["Johnson Controls"]},"summary":"Attackers can upload malicious files to Johnson Controls FM Systems Employee, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2026-21662/"}
