Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76855 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-2026-76855/ (Markdown: https://insights.sbomify.com/CVE-2026-76855/index.md)","id":"CVE-2026-76855","markdown":"https://insights.sbomify.com/CVE-2026-76855/index.md","name":"CVE-2026-76855","record":{"aliases":["GHSA-wpff-j8jq-xfhj"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Netcore router","requires_auth":"low_privilege","summary":"Attackers can access other users' session and browsing history data via audit endpoints in Netcore NR255-V routers.","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-359","name":"Exposure of Private Personal Information to an Unauthorized Actor"}],"description":"Netcore NR255-V version 1.5.130703 contains a sensitive information disclosure vulnerability in the audit endpoints handled by l7_web_auth_log_dump_cgi.c, audit_get_cgi.c, and mod_dispatch_auth/plan.json.
