Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-76872 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-2026-76872/ (Markdown: https://insights.sbomify.com/CVE-2026-76872/index.md)","id":"CVE-2026-76872","markdown":"https://insights.sbomify.com/CVE-2026-76872/index.md","name":"CVE-2026-76872","record":{"aliases":["GHSA-xrr8-q5hh-wh9p"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore router","requires_auth":"low_privilege","summary":"Attackers can inject persistent malicious scripts into the web management interface of Netcore NR255-V routers via DHCP and ACL pages, compromising other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/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":"Netcore NR255-V version 1.5.130703 contains a stored cross-site scripting vulnerability in DHCP static IP and IP ACL management pages, including dhcp_add_staticip_cgi, dhcp_staticip_show_cgi, ip_acl_set_cgi, and ip_acl_show_cgi.
