Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76857 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-2026-76857/ (Markdown: https://insights.sbomify.com/CVE-2026-76857/index.md)","id":"CVE-2026-76857","markdown":"https://insights.sbomify.com/CVE-2026-76857/index.md","name":"CVE-2026-76857","record":{"aliases":["GHSA-g7jc-f2x5-32j3"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore router firmware","requires_auth":"low_privilege","summary":"Attackers can access plaintext DDNS credentials via a CGI endpoint in Netcore NR255-V routers, exposing sensitive account information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"Netcore NR255-V firmware version 1.5.130703 contains a sensitive information disclosure vulnerability in the ddns_wan_list_show.cgi endpoint and related DDNSset_cgi, IGD_GetCgiHandler, and IGD_CgiCall components.
