CVE-2026-76274 is a server-side request forgery vulnerability in Splunk App for Splunk Observability Cloud affecting Splunk Enterprise 10.4.x before 10.4.3, 10.2.x before 10.2.7, and 10.0.x before 10.0.10. Insufficient validation of outbound-request destinations allows an authenticated user whose role includes the read_o11y_content capability to redirect a REST API-triggered request to an attacker-controlled host, exposing the configured Observability Cloud API token. Splunk Enterprise 9.4.x is not affected.
