CVE-2026-76297 · Severity: medium · CVSS 4.2 · Published 2026-10-21

Splunk Enterprise allows users to configure federated searches to retrieve data from remote Splunk deployments. An attacker can trick an administrator into visiting a malicious page that disables all federated search providers without the victim's knowledge, temporarily blocking access to remote data. This attack requires phishing the victim but could disrupt critical cross-site search operations.

## Technical details

The federated provider REST API in Splunk Enterprise accepts GET requests for state-changing operations, violating REST conventions and enabling cross-site request forgery (CSRF) attacks. An unauthenticated attacker can craft a malicious URL or embed it in a webpage to trick an authenticated user holding the edit_federated_providers capability into disabling all federated search providers. The user's browser automatically sends their session credentials with the request, allowing the attacker to change system state without valid authorization.

## Affected products

- Splunk Enterprise below 10.4.4, 10.2.8, 10.0.11, and 9.4.16
