Trend Micro Apex One/SEP Agent Origin Validation Privilege Escalation Vulnerability
Description
An origin validation vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations. This is similar to CVE-2026-34927 but exists in a different process protection mechanism. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
