Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-34491 in the wild and no public exploit code.\n\nAffected product: Johnson Controls Metasys 14. 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-2026-34491/ (Markdown: https://insights.sbomify.com/CVE-2026-34491/index.md)","id":"CVE-2026-34491","markdown":"https://insights.sbomify.com/CVE-2026-34491/index.md","name":"CVE-2026-34491","record":{"aliases":["GHSA-2fj7-6j2c-3972"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Building automation system","requires_auth":"low_privilege","summary":"Cross-site scripting in Johnson Controls Metasys allows attackers to inject malicious scripts, potentially compromising user sessions and data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Johnson Controls Metasys 14 and Johnson Controls Metasys 15 allows Cross Site Scripting.\n\nThis issue affects Metasys 14: before 14.1.5; Metasys 15: before 15.0.1.","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":"Cross-site scripting in Metasys 14","id":"CVE-2026-34491","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Airwall - Arbitrary file read","id":"CVE-2026-34492"},"packages":[],"prev":{"headline":"XAAP Android Data Stored in Unencrypted Database","id":"CVE-2026-34490"},"products":["Metasys 14","Metasys 15"],"published":"2026-08-24","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":"2026-08-25","vendors":["Johnson Controls"]},"summary":"Cross-site scripting in Johnson Controls Metasys allows attackers to inject malicious scripts, potentially compromising user sessions and data.","url":"https://insights.sbomify.com/CVE-2026-34491/"}
