Japanese cybersecurity software company Trend Micro has addressed an Apex One zero-day vulnerability exploited in attacks targeting Windows systems.
Apex One is Trend Micro's enterprise-grade endpoint security platform that protects corporate networks from a wide range of security threats, including malware, ransomware, fileless attacks, and web-based threats.
Tracked as CVE-2026-34926, this directory traversal vulnerability in the Apex One (on-premises) server allows local attackers with admin privileges to inject malicious code.
"A directory traversal vulnerability in the Apex One (on-premise) server could allow a pre-authenticated local attacker to modify a key table on the server to inject malicious code to deploy to agents on affected installations," Trend Micro saidon Thursday.
"This vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must have access to the Apex One Server and already obtained administrative credentials to the server via some other method to exploit this vulnerability."
