CVE-2026-76349
In Splunk Enterprise versions below 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user could trick an authenticated user into running arbitrary Search Processing Language (SPL) commands using the permissions of the authenticated user through a crafted Splunk Web link. The SPL commands could access all relevant data. The vulnerability does not affect Splunk Enterprise 10.4 versions and above. The vulnerability is possible because Splunk Web substitutes form token values supplied through the Uniform Resource Locator (URL) into SPL searches without neutralizing them.
Leer descripción completaMostrar menos
The vulnerability requires the attacker to phish the user by tricking them into opening the crafted link. The unauthenticated user should not be able to exploit the vulnerability at will. For more information see Token reference (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/simple-xml-dashboards/10.2/simple-xml-reference/token-reference) in the Splunk documentation.
