MR-GM5A-L1, published on 11 Mar 2026. 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-2026-27842 in the wild and no public exploit code.\n\nAffected product: Micro Research Ltd. MR-GM5A-L1. 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-2026-27842/ (Markdown: https://insights.sbomify.com/CVE-2026-27842/index.md)","id":"CVE-2026-27842","markdown":"https://insights.sbomify.com/CVE-2026-27842/index.md","name":"CVE-2026-27842","record":{"aliases":["GHSA-2m33-h63p-wx98"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Micro Research device","requires_auth":"none","summary":"An attacker can bypass authentication to modify device configuration on Micro Research MR-GM5L-S1 and MR-GM5A-L1 devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"Authentication bypass issue exists in MR-GM5L-S1 and MR-GM5A-L1, which may allow an attacker to bypass authentication and change the device configuration.","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":"Auth bypass in MR-GM5A-L1","id":"CVE-2026-27842","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"SenseLive X3050 Missing authentication for critical function","id":"CVE-2026-27843"},"packages":[],"prev":{"headline":"SenseLive X3050 Cross-Site request forgery","id":"CVE-2026-27841"},"products":["MR-GM5A-L1","MR-GM5L-S1"],"published":"2026-03-11","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-11","vendors":["Micro Research Ltd."]},"summary":"An attacker can bypass authentication to modify device configuration on Micro Research MR-GM5L-S1 and MR-GM5A-L1 devices.","url":"https://insights.sbomify.com/CVE-2026-27842/"}
