Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
CyberArk Endpoint Privilege Manager Agent through 25.10.0 allows a local user to achieve privilege escalation through policy elevation of an Administration task.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

CyberArk Endpoint Privilege Manager Agent through version 25.10.0 contains a local privilege escalation vulnerability where a local user can elevate privileges by manipulating policy elevation of an Administration task. This allows a standard local user to gain higher-level privileges through the EPM agent's policy configuration mechanism.

MitigationApply the vendor patch or upgrade to a version newer than 25.10.0 once released. Review and audit existing EPM policies for unauthorized changes and restrict local administrative access to the endpoint.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify EPM Agent is installed
    Check for CyberArk Endpoint Privilege Manager Agent in installed programs (Programs and Features) or check for the EPM service running on the system
    Affected if The CyberArk EPM Agent is installed on the endpoint
  2. Check installed EPM version
    Locate the EPM Agent installation directory and check the version file, or use 'Get-ItemProperty' on the uninstall registry key for CyberArk EPM to retrieve the version number
    Affected if The installed version is 25.10.0 or any version lower than 25.10.0 (the agent version is <= 25.10.0)
  3. Review EPM policy configurations for Administration tasks
    Access the EPM management console or policy configuration files to examine elevation rules for Administration tasks. Look for any policies that grant elevated privileges to standard local users
    Affected if There are policies that allow standard/local users to elevate privileges for Administration tasks, especially if these policies were modified without authorization
  4. Audit recent EPM policy changes
    Review EPM policy change logs or audit trails to identify any recent modifications to elevation policies, particularly those affecting Administration task elevation
    Affected if There are unauthorized or unexpected modifications to policy elevation settings for Administration tasks

The environment is affected if CyberArk Endpoint Privilege Manager Agent version 25.10.0 or lower is installed AND there are EPM policies that allow manipulation of Administration task elevation by local users.

Upgrade available Upgrade to a release after 25.10.0
Interim mitigation

Apply the vendor patch or upgrade to a version newer than 25.10.0 once released. Review and audit existing EPM policies for unauthorized changes and restrict local administrative access to the endpoint.

Recommended fix Moderate confidence

Upgrade to the fixed release of Endpoint Privilege Manager published by CyberArk (version higher than 25.10.0 - verify exact version in official CyberArk security advisory)

  1. 1. Identify all systems running CyberArk Endpoint Privilege Manager version 25.10.0 or earlier.
  2. 2. Contact CyberArk support or check the official CyberArk security advisory at docs.cyberark.com for the specific fixed version and upgrade instructions.
  3. 3. Plan and schedule an upgrade window following your organization's change management process.
  4. 4. Backup current Endpoint Privilege Manager configuration and policies.
  5. 5. Upgrade Endpoint Privilege Manager agent to the fixed version released by CyberArk.
  6. 6. Verify the upgrade was successful and test that privilege escalation is no longer possible through policy elevation.
  7. 7. Monitor for any post-upgrade issues and validate that existing policies function correctly.
Caveat Review CyberArk release notes for the fixed version for any potential compatibility or configuration changes that may affect existing policies
