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-2026-27871 in the wild and no public exploit code.\n\nAffected product: Johnson Controls TL280. 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-2026-27871/ (Markdown: https://insights.sbomify.com/CVE-2026-27871/index.md)","id":"CVE-2026-27871","markdown":"https://insights.sbomify.com/CVE-2026-27871/index.md","name":"CVE-2026-27871","record":{"aliases":["GHSA-jpq8-c4g8-9mq5"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Johnson Controls TL280","requires_auth":"none","summary":"A cryptographic weakness in Johnson Controls TL280 devices allows attackers to perform cryptanalytic attacks, potentially compromising data confidentiality.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jci","cpe":[],"cvss":{"score":2.9,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Cwe-327 Use of a Broken or Risky Cryptographic Algorithm vulnerability in Johnson Controls TL280 allows Cryptanalytic Attack.\n\nThis issue affects TL280: before 5.63.","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":"TL280","id":"CVE-2026-27871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"EasyIO FG","id":"CVE-2026-27872"},"packages":[],"prev":{"headline":"CROSS-SITE SCRIPTING (XSS) VIA MALICIOUS FILE UPLOAD ON REGESTA SMART HD-PLC OF TELDAT","id":"CVE-2026-27870"},"products":["TL280"],"published":"2026-08-14","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":"partial"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["Johnson Controls"]},"summary":"A cryptographic weakness in Johnson Controls TL280 devices allows attackers to perform cryptanalytic attacks, potentially compromising data confidentiality.","url":"https://insights.sbomify.com/CVE-2026-27871/"}
