An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54406 in the wild and no public exploit code.\n\nAffected product: Ubiquiti Inc UniFi Network Application. 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-2026-54406/ (Markdown: https://insights.sbomify.com/CVE-2026-54406/index.md)","id":"CVE-2026-54406","markdown":"https://insights.sbomify.com/CVE-2026-54406/index.md","name":"CVE-2026-54406","record":{"aliases":["GHSA-h9fm-m325-j8cf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"UniFi Network Application","requires_auth":"high_privilege","summary":"High-privilege network attackers can exploit path traversal in UniFi Network Application to escalate write permissions on the host.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"unifi_network_application","vendor":"ui"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A malicious actor with access to the network and high privileges could exploit a Path Traversal vulnerability found in self-hosted instances of UniFi Network Application to escalate write permission on the host device.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path traversal in UniFi Network Application","id":"CVE-2026-54406","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in UniFi Protect Application","id":"CVE-2026-54407"},"packages":[],"prev":{"headline":"Denial of service in UniFi Network Application","id":"CVE-2026-54405"},"products":["UniFi Network Application"],"published":"2026-07-02","related":[{"cvss_score":10,"headline":"Missing authorization in UniFi Network Application","id":"CVE-2023-41721","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":9.1,"headline":"Command injection in UniFi Network application","id":"CVE-2023-28365","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":8.8,"headline":"Privilege escalation in UniFi Network Application","id":"CVE-2026-55114","kev_date_added":null,"published":"2026-07-02"},{"cvss_score":8.3,"headline":"Privilege escalation in UniFi Network Application","id":"CVE-2026-55118","kev_date_added":null,"published":"2026-07-02"},{"cvss_score":7.8,"headline":"Command injection in UniFi Network Application","id":"CVE-2024-42025","kev_date_added":null,"published":"2024-09-13"},{"cvss_score":7.5,"headline":"Denial of service in UniFi Network Application","id":"CVE-2026-54405","kev_date_added":null,"published":"2026-07-02"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-02","vendors":["Ubiquiti Inc"]},"summary":"High-privilege network attackers can exploit path traversal in UniFi Network Application to escalate write permissions on the host.","url":"https://insights.sbomify.com/CVE-2026-54406/"}
