CVE-2026-26225: Intego Personal Backup

High severity, CVSS 8.5. EPSS: 0.2% chance of exploitation in the next 30 days.

Intego Personal Backup, a macOS backup utility that allows users to create scheduled backups and bootable system clones, contains a local privilege escalation vulnerability. Backup task definitions are stored in a location writable by non-privileged users while being processed with elevated privileges. By crafting a malicious serialized task file, a local attacker can trigger arbitrary file writes to sensitive system locations, leading to privilege escalation to root.

Affected products

• Intego Personal Backup: up to and including 10.9.0
