CVE-2026-2914: CyberArk EPM Privilege Escalation Flaw

CVE-2026-2914 Overview

CVE-2026-2914 is a privilege escalation vulnerability affecting CyberArk Endpoint Privilege Manager (EPM) Agent versions 25.10.0 and lower. The vulnerability allows authenticated local users to potentially achieve unauthorized privilege elevation by leveraging CyberArk elevation dialogs. This security flaw is classified under CWE-269 (Improper Privilege Management), indicating a fundamental issue in how the agent handles privilege requests and elevation workflows.

Critical Impact

Local attackers with low privileges can exploit elevation dialog mechanisms to gain unauthorized elevated access, potentially compromising endpoint security controls and gaining administrative privileges on affected systems.

Affected Products

• CyberArk Endpoint Privilege Manager Agent version 25.10.0
• CyberArk Endpoint Privilege Manager Agent versions lower than 25.10.0
• All systems running affected EPM Agent versions

Technical Details for CVE-2026-2914

Vulnerability Analysis

This vulnerability stems from improper privilege management within the CyberArk Endpoint Privilege Manager Agent. The elevation dialog mechanism, designed to provide controlled privilege escalation for authorized operations, contains a flaw that can be exploited by local attackers. The vulnerability requires local access to the affected system and low-level user privileges to initiate an attack.

The attack complexity is low, meaning exploitation does not require specialized conditions or significant preparation. Once exploited, attackers can achieve high impact across confidentiality, integrity, and availability of the affected endpoint. This makes CVE-2026-2914 particularly concerning for organizations relying on CyberArk EPM for endpoint privilege management and least-privilege security policies.

Root Cause

The root cause of CVE-2026-2914 is classified as CWE-269: Improper Privilege Management. The CyberArk EPM Agent's elevation dialog functionality does not adequately validate or restrict privilege requests, allowing attackers to manipulate the elevation workflow to gain privileges beyond their authorized scope. This type of vulnerability typically occurs when privilege escalation mechanisms fail to properly verify the legitimacy of elevation requests or when there are exploitable gaps in the privilege boundary enforcement.

Attack Vector

The attack vector for CVE-2026-2914 is local, requiring the attacker to have authenticated access to the target system. The exploitation process involves:

1. An authenticated low-privilege user accesses the affected CyberArk EPM Agent
2. The attacker interacts with the elevation dialog mechanism
3. Through manipulation of the elevation workflow, the attacker bypasses intended privilege restrictions
4. Successful exploitation results in unauthorized privilege elevation on the endpoint

The vulnerability does not require user interaction beyond the attacker's own actions, and no special attack timing or complex preparation is necessary. This local privilege escalation can be particularly damaging in environments where endpoint privilege management is a critical security control.

Detection Methods for CVE-2026-2914

Indicators of Compromise

• Unusual privilege elevation events originating from CyberArk EPM Agent elevation dialogs
• Unexpected administrative actions performed by standard user accounts on systems running vulnerable EPM Agent versions
• Anomalous process execution with elevated privileges that bypasses normal EPM policy enforcement
• Event logs showing privilege escalation patterns outside of approved EPM workflows

Detection Strategies

• Monitor Windows Security Event Logs for privilege escalation events (Event IDs 4672, 4673, 4674) associated with CyberArk EPM processes
• Implement endpoint detection rules to identify abnormal elevation dialog interactions
• Review CyberArk EPM audit logs for unauthorized or suspicious privilege elevation requests
• Deploy behavioral analysis to detect privilege escalation attempts that deviate from normal user patterns

Monitoring Recommendations

• Enable comprehensive audit logging for CyberArk EPM Agent activities on all managed endpoints
• Configure SIEM alerts for anomalous privilege elevation patterns tied to EPM Agent processes
• Establish baseline behavior for EPM elevation dialog usage to identify deviations
• Implement real-time monitoring of administrative privilege acquisitions across the enterprise

How to Mitigate CVE-2026-2914

Immediate Actions Required

• Inventory all systems running CyberArk Endpoint Privilege Manager Agent to identify vulnerable installations
• Prioritize patching for systems with sensitive data or critical business functions
• Implement additional access controls to limit local access to affected endpoints pending patch deployment
• Review and restrict EPM elevation policies to minimize exposure until updates are applied

Patch Information

CyberArk has addressed this vulnerability in versions newer than 25.10.0. Organizations should upgrade to the latest version of the CyberArk Endpoint Privilege Manager Agent as soon as possible. For detailed patch information and upgrade instructions, refer to the CyberArk EPM Release Notes and the CyberArk Product Security Information page.

Workarounds

• Restrict local access to systems running vulnerable EPM Agent versions to only essential personnel
• Implement additional endpoint monitoring to detect privilege escalation attempts
• Consider temporarily disabling or restricting elevation dialog functionality where operationally feasible
• Apply network segmentation to limit lateral movement potential from compromised endpoints
