CVE-2026-76267

Log Injection through the REST API in Splunk App for Splunk O11y Cloud

Description

In Splunk Enterprise versions below 10.4.3, 10.2.7, and 10.0.10, a user that holds a role with the read_o11y_content capability could inject forged entries into the app log through the Representational State Transfer (REST) API. The vulnerability is possible because Splunk App for Splunk O11y Cloud does not neutralize user-supplied SignalFlow content before writing it to the app log. Splunk Enterprise versions 9.4.x are not affected.
