It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-35867 exists.\n\nAffected product: LB-LINK AC1900 firmware. 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-2026-35867/ (Markdown: https://insights.sbomify.com/CVE-2026-35867/index.md)","id":"CVE-2026-35867","markdown":"https://insights.sbomify.com/CVE-2026-35867/index.md","name":"CVE-2026-35867","record":{"aliases":["GHSA-cw3c-9w3h-vf4q"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LB-LINK router firmware","requires_auth":"high_privilege","summary":"An attacker can execute arbitrary commands on LB-LINK AC1900 routers via shell metacharacters in a specific POST request without administrative access.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A Command Injection vulnerability exists in the bs_SetLimitCli_info function within the libshare.so library of the LB-LINK router AC1900_AZ2 V1.0.2 via shell metacharacters, if the device is deployed in a scenario where an actor is able to make a \"POST /goform/set_LimitClient_cfg\" call but does not already have administrative access to the device.","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":"Command injection in AC1900 firmware","id":"CVE-2026-35867","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":"Command injection in n/a","id":"CVE-2026-35868"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2026-35847"},"products":["AC1900 firmware"],"published":"2026-09-13","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["LB-LINK"]},"summary":"An attacker can execute arbitrary commands on LB-LINK AC1900 routers via shell metacharacters in a specific POST request without administrative access.","url":"https://insights.sbomify.com/CVE-2026-35867/"}
