CVE-2026-76362

Improper Certificate Validation through CyberArk Vault Privileged Access Manager in Splunk SOAR

Published Aug 19, 2026 CVSS 3.1 · 7.4 High EPSS < 1% KEV · Not listed
Description
In Splunk SOAR versions below 8.6.0, an unauthenticated user who can observe or alter network traffic between Splunk SOAR and a configured CyberArk Representational State Transfer (REST) server could access or modify all relevant data exchanged through that credential manager. The vulnerability is possible because the CyberArk REST client does not verify server certificates by default. The attack requires the attacker to have network-path interception capability between Splunk SOAR and the configured CyberArk REST server. For more information see Manage your organization's credentials with a password vault (https://help.splunk.com/en/splunk-soar/soar-cloud/administer-soar-cloud/configure-administration-settings-in-splunk-soar-cloud/manage-your-organizations-credentials-with-a-password-vault) in the Splunk documentation.

Remediation

Vendor Solution
