MR-GM5A-L1, published on 11 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20892 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-2026-20892/ (Markdown: https://insights.sbomify.com/CVE-2026-20892/index.md)","id":"CVE-2026-20892","markdown":"https://insights.sbomify.com/CVE-2026-20892/index.md","name":"CVE-2026-20892","record":{"aliases":["GHSA-8cjp-9cg5-vcjh"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Micro Research device","requires_auth":"high_privilege","summary":"Administrative users can execute arbitrary commands on Micro Research MR-GM5L-S1 and MR-GM5A-L1 devices due to a code injection flaw.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Code injection vulnerability exists in MR-GM5L-S1 and MR-GM5A-L1, which may allow an attacker with administrative privileges to execute arbitrary commands.","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":"Code injection in MR-GM5A-L1","id":"CVE-2026-20892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in Fujitsu Security Solution AuthConductor Client Basic V2","id":"CVE-2026-20893"},"packages":[],"prev":{"headline":"Auth bypass in Intel(R) PROSet/Wireless WiFi Software for Windows","id":"CVE-2026-20891"},"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-11","vendors":["Micro Research Ltd."]},"summary":"Administrative users can execute arbitrary commands on Micro Research MR-GM5L-S1 and MR-GM5A-L1 devices due to a code injection flaw.","url":"https://insights.sbomify.com/CVE-2026-20892/"}
