CVE-2026-34928: CWE-346: Origin Validation Error in Trend Micro, Inc. TrendAI Apex One
CVE-2026-34928 is a high-severity origin validation vulnerability in Trend Micro TrendAI Apex One/SEP agent version 2019 (14.0). It allows a local attacker with low-privileged code execution to escalate privileges via a named pipe communication mechanism. This issue is related to improper origin validation (CWE-346) and is similar to CVE-2026-34927 but involves a different named pipe. No official patch or remediation guidance is currently available, and no known exploits exist in the wild.
AI Analysis
Technical Summary
CVE-2026-34928 is an origin validation error vulnerability (CWE-346) affecting Trend Micro TrendAI Apex One/SEP agent version 2019 (14.0). The flaw allows a local attacker who already has low-privileged code execution on the affected system to escalate privileges by exploiting a named pipe communication mechanism. This vulnerability is similar in nature to CVE-2026-34927 but targets a different named pipe. The CVSS v3.1 base score is 7.8, indicating high severity. As of the published date, no official patch or remediation guidance has been provided by Trend Micro, and no known exploits have been observed in the wild.
Potential Impact
An attacker with existing low-privileged code execution on a system running the affected Trend Micro TrendAI Apex One/SEP agent can escalate their privileges, potentially gaining higher-level access. This could lead to full system compromise, including confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
No official patch or remediation guidance is currently available from the vendor. Organizations should monitor Trend Micro advisories for updates. Until a fix is released, restricting local access to trusted users and limiting low-privileged code execution opportunities may reduce risk.
