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-2026-76940 in the wild and no public exploit code.\n\nAffected product: Ebyte NA111-M 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-2026-76940/ (Markdown: https://insights.sbomify.com/CVE-2026-76940/index.md)","id":"CVE-2026-76940","markdown":"https://insights.sbomify.com/CVE-2026-76940/index.md","name":"CVE-2026-76940","record":{"aliases":["GHSA-cw56-r7cc-wcx4"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Ebyte NA111-M Firmware","requires_auth":"none","summary":"Attackers can perform brute-force attacks on Ebyte NA111-M devices due to missing rate limiting, potentially leading to unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"The affected Ebyte device does not restrict repeated authentication \nattempts through rate limiting or account lockout mechanisms.
