Vulnerability in Splunk Enterprise (CVE-2026-76323)
Summary
Vulnerability in Splunk Enterprise (CVE-2026-76323). Confidential information can be exposed externally.
Original description
The description as published by the source.
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could bypass Search Processing Language (SPL) safeguards for risky commands through the Job Details dashboard. The injected SPL could run using the permissions of an authenticated user who opens a crafted Job Details dashboard link. This could allow access to all relevant data and affect system integrity within those permissions. The vulnerability is possible because the Job Details dashboard does not correctly neutralize a caller-supplied search identifier before placing it into SPL searches. The vulnerability requires the attacker to phish the user by tricking them into opening the crafted link. The user who does not hold the "admin" or "power" Splunk roles should not be able to exploit the vulnerability at will.
