An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-21659 in the wild and no public exploit code.\n\nAffected product: Johnson Controls Frick Controls Quantum HD. 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-2026-21659/ (Markdown: https://insights.sbomify.com/CVE-2026-21659/index.md)","id":"CVE-2026-21659","markdown":"https://insights.sbomify.com/CVE-2026-21659/index.md","name":"CVE-2026-21659","record":{"aliases":["GHSA-7qxc-43wm-v793"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial control system","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code and read sensitive data via Local File Inclusion in Johnson Controls Frick Quantum HD devices.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[{"product":"frick_controls_quantum_hd_firmware","vendor":"johnsoncontrols"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"Unauthenticated Remote Code Execution and Information Disclosure due to Local File Inclusion (LFI) vulnerability in Johnson Controls Frick Controls Quantum HD allow an unauthenticated attacker to\nexecute arbitrary code on the affected device, leading to full system compromise. \nThis issue affects Frick Controls Quantum HD: Frick Controls Quantum HD version 10.22 and prior.","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":"Path traversal in Frick Controls Quantum HD","id":"CVE-2026-21659","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Johnson Controls-Frick Quantum HD-Hardcoded Email Credentials Saved as Plaintext in Firmware","id":"CVE-2026-21660"},"packages":[],"prev":{"headline":"Johnson Controls -Frick Quantum HD- Unauthenticated Remote Code Execution","id":"CVE-2026-21658"},"products":["Frick Controls Quantum HD"],"published":"2026-02-27","related":[{"cvss_score":8.8,"headline":"Johnson Controls -Frick Quantum HD- Unauthenticated Remote Code Execution","id":"CVE-2026-21654","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8.8,"headline":"Johnson Controls -Frick Quantum HD- Unauthenticated Remote Code Execution","id":"CVE-2026-21656","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8.8,"headline":"Johnson Controls -Frick Quantum HD- Unauthenticated Remote Code Execution","id":"CVE-2026-21657","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":8.8,"headline":"Johnson Controls -Frick Quantum HD- Unauthenticated Remote Code Execution","id":"CVE-2026-21658","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":6.9,"headline":"Johnson Controls-Frick Quantum HD-Hardcoded Email Credentials Saved as Plaintext in Firmware","id":"CVE-2026-21660","kev_date_added":null,"published":"2026-02-27"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-06","vendors":["Johnson Controls"]},"summary":"Unauthenticated attackers can execute arbitrary code and read sensitive data via Local File Inclusion in Johnson Controls Frick Quantum HD devices.","url":"https://insights.sbomify.com/CVE-2026-21659/"}
