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-2026-45207 but exists in a different process protection communication 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.
AnalysisAI
Local privilege escalation in Trend Micro Apex One and Apex One as a Service allows low-privileged attackers to elevate to higher privileges by abusing an origin validation weakness (CWE-346) in one of the agent's process protection communication mechanisms. The flaw is a sibling issue to CVE-2026-45207 affecting a different IPC channel and is reported by Trend Micro itself; no public exploit identified at time of analysis and the CVE is not on CISA KEV.
