# CVE-2026-107246: CVE-2026-107246

Status: published. Published: 2026-11-10. Updated: 2026-11-10.

The Plesk extension "Site Import" before 1.13.2 does not properly validate domain and session identifiers, allowing path traversal. This lets a non-owner subscription user redirect a privileged backend session into a directory they control, resulting in arbitrary code execution as root.
