CVE-2026-76362Network attack vector

Credential disclosure and tampering via unchecked certificates

Published Aug 19, 2026 · Updated Aug 21, 2026

Improper certificate validation in Splunk SOAR before 8.6.0 allows remote attackers to read or modify CyberArk REST credential-manager traffic. The CyberArk REST client leaves server-certificate verification disabled by default, accepting an untrusted endpoint during vault exchanges. Exploitation requires network-path interception between SOAR and a configured CyberArk REST server and exposes all data carried by that manager.
