Splunk Enterprise: Auth Bypass via /services/streams/search REST q param<10.0.1)
CVE-2025-20379 Published on November 12, 2025
Risky command safeguards bypass using the “/services/streams/search“ REST endpoint through “q“ parameter in Splunk Enterprise
In Splunk Enterprise versions below 10.0.1, 9.4.5, 9.3.7, and 9.2.9 and Splunk Cloud Platform versions below 9.3.2411.116, 9.3.2408.124, 10.0.2503.5 and 10.1.2507.1, a low-privileged user that does not hold the admin or power Splunk roles could run a saved search with a risky command using the permissions of a higher-privileged user to bypass the SPL safeguards for risky commands. They could bypass these safeguards on the /services/streams/search endpoint through its q parameter by circumventing endpoint restrictions using character encoding in the REST path. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.
