CVE-2026-26225
HighSummary
Intego Personal Backup, a macOS backup utility, 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.
Risk Assessment
The risk includes full system compromise by a local user, potentially leading to data theft or malware installation. An attacker can gain unrestricted access to the system.
Recommendation
It is recommended to update Intego Personal Backup to the latest patched version. Also, restrict access to the storage location of task definitions and apply the principle of least privilege.
