An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76869 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-2026-76869/ (Markdown: https://insights.sbomify.com/CVE-2026-76869/index.md)","id":"CVE-2026-76869","markdown":"https://insights.sbomify.com/CVE-2026-76869/index.md","name":"CVE-2026-76869","record":{"aliases":["GHSA-pm8m-93fr-93q6"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore router","requires_auth":"high_privilege","summary":"Attackers can exploit a stack-based buffer overflow in the reboot timer CGI to corrupt memory, potentially leading to code execution or denial of service on Netcore NR255-V routers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in reboot_timer_set.cgi caused by improper sscanf token parsing.
