An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-27849 exists.\n\nAffected product: Linksys MR9600. 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-2026-27849/ (Markdown: https://insights.sbomify.com/CVE-2026-27849/index.md)","id":"CVE-2026-27849","markdown":"https://insights.sbomify.com/CVE-2026-27849/index.md","name":"CVE-2026-27849","record":{"aliases":["GHSA-f2jw-4mh9-f63v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linksys mesh router","requires_auth":"none","summary":"Attackers can inject OS commands via TLS-SRP update functionality in Linksys mesh routers, leading to remote code execution.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ENISA","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Due to missing neutralization of special elements, OS commands can be injected via the update functionality of a TLS-SRP connection, which is normally used for configuring devices inside the mesh network.\nThis issue affects MR9600: 1.0.4.205530; MX4200: 1.0.13.210200.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Missing neutralization in Linksys MR9600, Linksys MX4200","id":"CVE-2026-27849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improper verification in Linksys MR9600, Linksys MX4200","id":"CVE-2026-27850"},"packages":[],"prev":{"headline":"Missing neutralization in Linksys MR9600, Linksys MX4200","id":"CVE-2026-27848"},"products":["MR9600","MX4200"],"published":"2026-02-25","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["Linksys"]},"summary":"Attackers can inject OS commands via TLS-SRP update functionality in Linksys mesh routers, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-27849/"}
