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-2026-28253 in the wild and no public exploit code.\n\nAffected product: Trane Tracer Concierge. 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-2026-28253/ (Markdown: https://insights.sbomify.com/CVE-2026-28253/index.md)","id":"CVE-2026-28253","markdown":"https://insights.sbomify.com/CVE-2026-28253/index.md","name":"CVE-2026-28253","record":{"aliases":["GHSA-c7pr-383r-xgg3"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Building automation system","requires_auth":"none","summary":"An unauthenticated attacker can cause a denial-of-service condition in Trane Tracer SC, SC+, and Concierge systems via excessive memory allocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"tracer_concierge","vendor":"trane"},{"product":"tracer_sc\\+_firmware","vendor":"trane"},{"product":"tracer_sc_firmware","vendor":"trane"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"A Memory Allocation with Excessive Size Value vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge could allow an unauthenticated attacker to cause a denial-of-service condition","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":"Memory Allocation with Excessive Size Value vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28253","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing Authorization vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28254"},"packages":[],"prev":{"headline":"Use of a Broken or Risky Cryptographic Algorithm vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28252"},"products":["Tracer Concierge","Tracer SC","Tracer SC+"],"published":"2026-03-12","related":[{"cvss_score":9.9,"headline":"Trane Tracer Code Injection","id":"CVE-2021-38450","kev_date_added":null,"published":"2021-10-27"},{"cvss_score":9.2,"headline":"Use of a Broken or Risky Cryptographic Algorithm vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28252","kev_date_added":null,"published":"2026-03-12"},{"cvss_score":8.2,"headline":"Use of Hard-coded Credentials vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28255","kev_date_added":null,"published":"2026-03-12"},{"cvss_score":6.9,"headline":"Missing Authorization vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28254","kev_date_added":null,"published":"2026-03-12"},{"cvss_score":6.9,"headline":"Use of Hard-coded Credentials vulnerability in Trane Tracer SC, Tracer SC+, and Tracer Concierge","id":"CVE-2026-28256","kev_date_added":null,"published":"2026-03-12"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-03-13","vendors":["Trane"]},"summary":"An unauthenticated attacker can cause a denial-of-service condition in Trane Tracer SC, SC+, and Concierge systems via excessive memory allocation.","url":"https://insights.sbomify.com/CVE-2026-28253/"}
