Path traversal via WebDAV/zrok paths enables arbitrary file writes outside the destination root, allowing file overwrite and potential remote code execution.
Patch when possible
- affected>= 0.4.23 and < 2.0.3
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
