CVE-2026-45576

HIGH

zrok copy writes attacker-controlled WebDAV paths outside the destination root

Title source: cna
STIX 2.1

Description

zrok is software for sharing web services, files, and network resources. From 0.4.23 until 2.0.3, `zrok2 copy` stores attacker-controlled WebDAV or zrok drive paths such as /../outside.txt in the source inventory and passes them to FilesystemTarget.WriteStream, allowing the sync pipeline to write files outside the selected local filesystem destination root. This issue is fixed in version 2.0.3.
