Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-72841 exists.\n\nAffected product: openwrt luci. 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-2026-72841/ (Markdown: https://insights.sbomify.com/CVE-2026-72841/index.md)","id":"CVE-2026-72841","markdown":"https://insights.sbomify.com/CVE-2026-72841/index.md","name":"CVE-2026-72841","record":{"aliases":["GHSA-x5wv-6f33-ph3p"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenWrt web interface","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit path traversal in OpenWrt's OpenVPN plugin to upload malicious files and achieve persistent root code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"luci-app-openvpn fails to properly validate the instance_name2 parameter during file upload, allowing authenticated users to perform path traversal and write arbitrary files outside the intended directory.
