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. This issue is fixed in version 2.4.3.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","score":6.3,"severity":null}],"references":["https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-jrq7-xrjx-pcfw","https://github.com/0xJacky/nginx-ui/commit/f92218e01054491fc1e6684dc6f7facaf8ab41eb","https://github.com/0xJacky/nginx-ui/releases/tag/v2.4.3"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-97860","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 12, 2026, 8:44:39 PM","dateUpdated":"Oct 13, 2026, 8:24:05 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
