What is CVE-2026-76361?
CVE-2026-76361 is a low-severity server-side request forgery vulnerability in Splunk SOAR, published on 19 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
In Splunk SOAR versions below 8.6.0, a user with the "Administrator" role could use the /rest/support/connectivity/.../check_connectivity endpoint to make Splunk SOAR initiate outbound network connections to arbitrary destinations and determine whether internal hosts and ports are reachable. The Server-Side Request Forgery (SSRF) is possible because the connectivity check REST API does not sufficiently validate the destination before Splunk SOAR connects to it.
