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-2026-111712 in the wild and no public exploit code.\n\nAffected product: Netcore NR256CN. 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-2026-111712/ (Markdown: https://insights.sbomify.com/CVE-2026-111712/index.md)","id":"CVE-2026-111712","markdown":"https://insights.sbomify.com/CVE-2026-111712/index.md","name":"CVE-2026-111712","record":{"aliases":["GHSA-5r7c-rr63-2rwm"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore router","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication on Netcore NR256CN routers by prefixing URIs with public routes to access protected management handlers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"Netcore NR256CN through 1.5.140116 contains an authentication bypass vulnerability that allows unauthenticated attackers to reach protected management CGI handlers by prefixing the URI with a public route.
