CVE-2026-107246 PUBLISHED

Assigner: hackerone
Reserved: 07.10.2026 Published: 10.11.2026 Updated: 10.11.2026

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.
