An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-76864 in the wild and no public exploit code.\n\nAffected product: Netcore NR255-V. 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-2026-76864/ (Markdown: https://insights.sbomify.com/CVE-2026-76864/index.md)","id":"CVE-2026-76864","markdown":"https://insights.sbomify.com/CVE-2026-76864/index.md","name":"CVE-2026-76864","record":{"aliases":["GHSA-pgr6-p5qf-2942"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore router","requires_auth":"high_privilege","summary":"Attackers can inject persistent scripts via QoS rule names, leading to code execution when viewed by administrators.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"NR255-V version 1.5.130703 fails to sanitize QoS rule names before they are parsed via eval() in qos_xianz_add_cgi, qos_xianz_show_cgi, qos_filter_add_cgi, and qos_filter_show_cgi handlers.
