Prior to version 2.0.2, the zrok WebDAV drive backend (davServer.Dir) restricts path traversal through lexical normalization but does not prevent symlink following. When a symbolic link inside the shared DriveRoot points to a location outside that root, remote WebDAV consumers can read files and—on shares without OS-level permission restrictions—write or overwrite files anywhere on the host filesystem accessible to the zrok process. This issue has been patched in version 2.0.2.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N","score":8.7,"severity":null}],"references":["https://github.com/openziti/zrok/security/advisories/GHSA-74m3-9qvm-rp9h","https://github.com/openziti/zrok/commit/459bcfc1e121decae1b1d11c37ad94e4ed5bbf2e","https://github.com/openziti/zrok/releases/tag/v2.0.2"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-28511","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"May 8, 2026, 3:45:57 AM","dateUpdated":"May 8, 2026, 12:13:21 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
