CVE-2026-45207: CWE-346: Origin Validation Error in Trend Micro, Inc. TrendAI Apex One
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.
AI Analysis
Technical Summary
CVE-2026-45207 is an origin validation error (CWE-346) affecting the Trend Micro TrendAI Apex One agent. The vulnerability impacts a process protection communication mechanism distinct from a related issue (CVE-2026-45206). It enables a local attacker with low privileges to escalate privileges by exploiting improper origin validation. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high impact on confidentiality, integrity, and availability. No vendor remediation or patch is currently available, and no exploitation in the wild has been reported.
Potential Impact
Successful exploitation allows a local attacker with low privileges to escalate their privileges on the affected system, potentially leading to full system compromise affecting confidentiality, integrity, and availability. However, exploitation requires prior ability to execute low-privileged code locally.
Mitigation Recommendations
No official patch or remediation guidance has been provided by the vendor. 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.
