CVE-2025-53378 is a missing authentication vulnerability in Trend Micro Worry-Free Business Security Services (WFBSS) SaaS agent that allows unauthenticated remote attackers to take control of affected agents with user interaction required. The vulnerability has a CVSS score of 7.6 (High) and affects only the cloud-based SaaS version of WFBSS, not on-premises deployments. Trend Micro has addressed this issue through a monthly maintenance update, and affected customers on the regular SaaS deployment schedule are automatically patched; no additional customer action is required for remediation.
An uncontrolled search path vulnerability in the Trend Micro Worry-Free Business Security Services (WFBSS) agent could have allowed an attacker with physical access to a machine to execute arbitrary code on affected installations. An attacker must have had physical access to the target system in order to exploit this vulnerability due to need to access a certain hardware component. Also note: this vulnerability only affected the SaaS client version of WFBSS only, meaning the on-premise version of Worry-Free Business Security was not affected, and this issue was addressed in a previous WFBSS monthly maintenance update. Therefore no other customer action is required to mitigate if the WFBSS agents are on the regular SaaS maintenance deployment schedule and this disclosure is for informational purposes only.
CVE-2025-49154 is an insecure access control vulnerability (CWE-284) in Trend Micro Apex One and Worry-Free Business Security that allows a local attacker with low-privileged code execution to overwrite critical memory-mapped files, potentially compromising system security and stability. With a CVSS score of 8.7 and low attack complexity, this vulnerability poses a significant risk to enterprise security postures, though exploitation requires prior code execution access. No active KEV confirmation or public POC availability is documented in standard vulnerability databases at this time.
