SQLi in Splunk Enterprise<10.4.3 SPL2 module filtering via REST API
CVE-2026-76270 Published on October 7, 2026
Structured Query Language (SQL) Injection in the SPL2 Module Catalog in Splunk Enterprise
In Splunk Enterprise versions below 10.4.3, a user that holds a role with the list_spl2_modules capability could use SQL injection in SPL2 module filtering to access all relevant data available through the affected Representational State Transfer (REST) API, including private SPL2 module definitions belonging to other users. The vulnerability is possible because Splunk Enterprise and Splunk Cloud Platform do not parameterize user-supplied values before using them in database queries for SPL2 module filtering.
