CVE-2026-45207

Apex · Apex One/SEP agent

An origin validation vulnerability in the Apex One/SEP agent allows local attackers to bypass security checks and escalate privileges.

Executive summary

Improper origin validation in the Apex One/SEP agent allows local attackers to perform unauthorized actions and escalate privileges.

Vulnerability

This vulnerability involves the failure of the Apex One/SEP agent to properly validate the origin of requests or data. An authenticated local attacker can leverage this to bypass internal security controls and execute privileged operations.

Business impact

By exploiting this origin validation flaw, an attacker can subvert the agent's security logic, potentially leading to unauthorized access to the host system. The CVSS score of 7.8 confirms that this is a high-severity issue capable of compromising the confidentiality, integrity, and availability of affected endpoints.

Remediation

Immediate Action: Update the Apex One/SEP agent to the latest version released by the vendor to ensure proper origin validation is enforced.

Proactive Monitoring: Review security agent logs for irregular communication patterns or unauthorized inter-process requests that deviate from established baselines.

Compensating Controls: Utilize host-based intrusion prevention systems (HIPS) to detect and block unauthorized attempts to interact with security agent services.

Exploitation status

Public Exploit Available: false

Analyst recommendation

This vulnerability highlights a critical failure in the agent's ability to verify the source of requests. Administrators are strongly advised to apply vendor-provided patches immediately to close the validation gap and mitigate the risk of local privilege escalation.
