What is CVE-2026-76264?

In certain versions of Splunk Enterprise, users without sufficient permissions (admin or power roles) can exploit a configuration oversight to create or modify scripted lookup definitions. This occurs because the system fails to enforce proper access controls on raw transforms configuration write paths, allowing unauthorized changes to be made via external lookup capabilities. Organizations using vulnerable versions should assess their security policies and patch accordingly to mitigate this risk.

Affected Version(s)

Splunk Enterprise 10.4 < 10.4.2

Splunk Enterprise 10.2 < 10.2.6

Splunk Enterprise 10.0 < 10.0.10
