CVE-2026-2914 is a privilege escalation in CyberArk Software, a Palo Alto Networks Company Endpoint Privilege Manager Agent. The fix is to apply the vendor patch noted below.

What is CVE-2026-2914?

CyberArk Endpoint Privilege Manager Agent versions 25.10.0 and lower allow potential unauthorized privilege elevation leveraging CyberArk elevation dialogs The CVSS base score is 8.5 (High), which puts this in the upper risk band and warrants a fast patch cycle. The official advisory is at https://www.cyberark.com/product-security/.

Am I affected?

Check the version of Endpoint Privilege Manager Agent you are running and compare it against the Affected row above (Endpoint Privilege Manager Agent 25.10 to <25.12). If your build sits inside the affected range, you must patch.

Run the version check that fits your platform:

# Linux package check
dpkg -s endpoint-privilege-manager-agent 2>/dev/null | grep -i ^Version
rpm -q endpoint-privilege-manager-agent 2>/dev/null
command -v endpoint-privilege-manager-agent >/dev/null && endpoint-privilege-manager-agent --version 2>/dev/null

# Windows (PowerShell)
Get-Package -Name "*Endpoint Privilege Manager Agent*" -ErrorAction SilentlyContinue | Select-Object Name, Version
winget list --name "Endpoint Privilege Manager Agent" 2>$null

How to fix CVE-2026-2914

Upgrade Endpoint Privilege Manager Agent to a patched build: See vendor advisory. The vendor advisory is the source of truth for the exact fixed version.

Ubuntu / Debian

sudo apt-get update
sudo apt-get install --only-upgrade endpoint-privilege-manager-agent
dpkg -s endpoint-privilege-manager-agent | grep -i ^Version

RHEL / CentOS / Rocky / AlmaLinux

sudo dnf upgrade --refresh endpoint-privilege-manager-agent -y
# or for older releases:
sudo yum update endpoint-privilege-manager-agent -y
rpm -q endpoint-privilege-manager-agent

SUSE / openSUSE

sudo zypper refresh
sudo zypper update endpoint-privilege-manager-agent
rpm -q endpoint-privilege-manager-agent

If you can't patch immediately

Apply at least one of the following inline controls until you can deploy the patched build. None replace the upgrade.

Restrict exposure with nftables (Linux)

# Allow only trusted CIDR to reach the affected service ports
sudo nft add table inet filter 2>/dev/null || true
sudo nft 'add chain inet filter input { type filter hook input priority 0 ; }' 2>/dev/null || true
sudo nft 'add rule inet filter input tcp dport {80, 443} ip saddr != 10.0.0.0/8 drop'
sudo nft list ruleset

Block at the host firewall (Windows)

New-NetFirewallRule -DisplayName "Block-CVE-2026-2914" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-2914"

Disable the affected service (Linux)

sudo systemctl stop endpoint-privilege-manager-agent 2>/dev/null || true
sudo systemctl disable endpoint-privilege-manager-agent 2>/dev/null || true

If the vendor advisory lists an official workaround, prefer that wording verbatim. If no workaround is published, the only safe remediation is the patch.

How to verify the fix worked

After upgrading, confirm the installed version matches the patched build and that no old library is still loaded by a long-running process.

# Linux
dpkg -s endpoint-privilege-manager-agent 2>/dev/null | grep -i ^Version
rpm -q endpoint-privilege-manager-agent 2>/dev/null || true
# Pid map check for old library handles
sudo lsof +c0 2>/dev/null | grep -i "DEL.*lib" || true

# Windows
Get-Package -Name "*Endpoint Privilege Manager Agent*" | Select-Object Name, Version
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5

Expected: the reported version is at or above See vendor advisory. Restart the affected service (systemctl restart <service> on Linux, or restart the Windows service) so it loads the patched binary.

Is CVE-2026-2914 actively exploited?

There is no public confirmation of exploitation in the wild listed in CISA KEV at the time of this writing. Patch anyway. Public exploits commonly follow disclosure within weeks.

Do I need to reboot after patching CVE-2026-2914?

For kernel and OS-level updates, yes. For most userland packages a systemctl restart <service> is enough on Linux, and restarting the Windows service or app on Windows. Any process that loaded the old library keeps using it until restarted.

What is the CVSS score for CVE-2026-2914?

8.5 (High). Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N.
