Sensitive search result disclosure via guessed Search ID in Splunk background jobs
CVE-2025-20366 is an access control / information disclosure vulnerability in Splunk Enterprise and Splunk Cloud Platform. In Splunk Enterprise versions below 9.4.4, 9.3.6, and 9.2.8, and Splunk Cloud Platform versions below 9.3.2411.111, 9.3.2408.119, and 9.2.2406.122, a low-privileged user who does not have the admin or power roles can access the results of an administrative search job that is running in the background. Exploitation requires the attacker to guess the unique Search ID (SID) associated with that job; if the SID is correctly guessed, the attacker can retrieve the job results despite lacking the intended privileges. The issue is therefore an authorization weakness tied to direct access to a job resource identified by SID, resulting in exposure of sensitive search results.
