CVE-2026-76332SPL Injection through Splunk Web in Splunk Enterprise
High 7.1
In plain English
A high-severity improper input validation in Splunk Enterprise from Splunk. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 27% of all known vulnerabilities).
Official description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user could trick an authenticated user into opening a crafted link to Analytics Workspace. When the authenticated user opens the link, Splunk Enterprise runs attacker-controlled Search Processing Language (SPL) using the permissions of that user. The injected SPL could access data and perform actions available to that user. The vulnerability is possible because Analytics Workspace does not sufficiently validate data used to build searches. 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.
