CVE-2026-76270 is a SQL injection vulnerability in SPL2 module catalog filtering caused by failure to parameterize user-supplied values before incorporating them into database queries. A user whose role includes the list_spl2_modules capability can exploit filtering to access all relevant data exposed through the affected REST API, including private SPL2 module definitions belonging to other users. Splunk Enterprise 10.4.x releases before 10.4.3 are affected; the 10.2.x, 10.0.x, and 9.4.x branches are unaffected. Splunk Cloud Platform is also identified as having the vulnerable query handling, but affected Cloud versions are unspecified.
