Organizations should monitor vendor advisories for updates. Since exploitation requires local code execution, restricting local access and applying the principle of least privilege may reduce risk until a fix is available.
Description
CVE-2026-45207 is a high-severity origin validation vulnerability in the Trend Micro TrendAI Apex One agent (version 2019, 14.0). It allows a local attacker with low privileges to escalate their privileges on the affected system. Exploitation requires the attacker to already have the ability to execute low-privileged code locally. No official patch or remediation guidance has been provided by the vendor at this time. There are no known exploits reported in the wild.
