Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84320 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/0xJacky/Nginx-UI (Go): affected all versions; fixed in 1.9.10-0.20260715121709-f92218e01054\n- github.com/0xJacky/Nginx-UI (Go): affected all versions; fixed in 1.9.10-0.20260715121709-f92218e01054\n- github.com/0xJacky/Nginx-UI (Go): affected all versions; fixed in 1.9.10-0.20260715121709-f92218e01054\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-2026-84320/ (Markdown: https://insights.sbomify.com/CVE-2026-84320/index.md)","id":"CVE-2026-84320","markdown":"https://insights.sbomify.com/CVE-2026-84320/index.md","name":"CVE-2026-84320","record":{"aliases":["GHSA-jrq7-xrjx-pcfw","GO-2026-6788"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nginx web UI","requires_auth":"low_privilege","summary":"An authenticated user can exploit path traversal in backup naming to write files outside the validated directory, potentially achieving code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.3, Nginx UI validates an automatic backup's storage_path, but AutoBackup.GetName returns a user-controlled name without rejecting path separators or parent-directory components, and downstream filename formatting embeds that result in the final archive filename. An authenticated user who can create or modify an automatic backup can cause filepath.Join to resolve the generated archive path outside the validated storage directory, allowing backup archives to be written with the Nginx UI process privileges. For encrypted configuration backups, the adjacent encryption key file can also be written outside the validated directory.
