Car Alarm System KE700, published on 15 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-2540 in the wild and no public exploit code.\n\nAffected product: Micca Auto Electronics Co., Ltd. Car Alarm System KE700. 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-2026-2540/ (Markdown: https://insights.sbomify.com/CVE-2026-2540/index.md)","id":"CVE-2026-2540","markdown":"https://insights.sbomify.com/CVE-2026-2540/index.md","name":"CVE-2026-2540","record":{"aliases":["GHSA-822c-h5gx-7pw7"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Car Alarm System","requires_auth":"none","summary":"Attackers can replay captured rolling codes to bypass authentication and clone alarm keys, gaining unauthorized vehicle access.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ASRG","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:N/SC:L/SI:L/SA:H/V:D/RE:M","version":"4.0"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"The Micca KE700 system contains flawed resynchronization logic and is vulnerable to replay attacks. This attack requires sending two previously captured codes in a specific sequence. As a result, the system can be forced to accept previously used (stale) rolling codes and execute a command. Successful exploitation allows an attacker to clone the alarm key. This grants the attacker unauthorized access to the vehicle to unlock or lock the doors.","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":"Micca KE700 Acceptance of previously used rolling codes","id":"CVE-2026-2540","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Micca KE700 Brute-force vulnerability due to low entropy","id":"CVE-2026-2541"},"packages":[],"prev":{"headline":"Micca KE700 Cleartext transmission of key fob ID","id":"CVE-2026-2539"},"products":["Car Alarm System KE700"],"published":"2026-02-15","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":"2026-02-17","vendors":["Micca Auto Electronics Co., Ltd."]},"summary":"Attackers can replay captured rolling codes to bypass authentication and clone alarm keys, gaining unauthorized vehicle access.","url":"https://insights.sbomify.com/CVE-2026-2540/"}
