Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76853 in the wild and no public exploit code.\n\nAffected product: Netcore NR268. 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-2026-76853/ (Markdown: https://insights.sbomify.com/CVE-2026-76853/index.md)","id":"CVE-2026-76853","markdown":"https://insights.sbomify.com/CVE-2026-76853/index.md","name":"CVE-2026-76853","record":{"aliases":["GHSA-6mhv-w69c-76fg"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore NR268 router","requires_auth":"low_privilege","summary":"Attackers can bypass security checks in the restore archive handling of Netcore NR268 routers, potentially allowing unauthorized configuration changes.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-353","name":"Missing Support for Integrity Check"}],"description":"Netcore NR268 firmware version 1.7.121109 contains a security check bypass vulnerability in the parame_put_file.cgi restore archive prefix validation.
