| Exploitation Conditions | Exploitation requires a valid Splunk Enterprise account that does not hold the 'admin' or 'power' role - meaning low-privileged users such as read-only analysts or custom-role users are the threat actors. The attacker must have network access to the Splunk REST API (typically TCP 8089 or the configured management port). The vulnerability is triggered via the saved-search dispatch endpoint; deployments that restrict API access to trusted networks or require elevated roles for dispatch operations reduce exposure. Exploitation is limited to the authenticated user context - unauthenticated access is not possible. The CVSS vector PR:L confirms authentication is required, distinguishing this from an external, pre-auth attack. |
| Impact | The CVSS 3.1 score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) accurately reflects a high-severity issue that is straightforward to exploit for any authenticated Splunk user. The low privilege requirement (PR:L) is the key limiting factor - this is not an unauthenticated attack, but in enterprise deployments, Splunk often has hundreds of low-privileged users (analysts, read-only consumers) who would ordinarily not have access to sensitive indexed data from other teams or tenants. The network attack vector and low complexity make exploitation trivially automatable once credentials are obtained. No EPSS data was provided in the source intelligence; no CISA KEV listing exists for this CVE, and no public proof-of-concept code has been reported, suggesting exploitation remains opportunistic rather than confirmed in the wild. The high confidentiality and integrity impact ratings are consistent with the description: an attacker can read all indexed data and manipulate saved-search behavior, which in a SOC or data analytics context is a critical business risk. Availability is not impacted per CVSS and the description supports this. Overall this should be treated as a genuine priority for any multi-tenant or large Splunk deployment. |
| Exploit ScenarioDerived | An attacker holding a low-privileged Splunk analyst account - one without the 'admin' or 'power' role - submits a crafted saved-search dispatch request to the Splunk REST API, embedding injected SPL commands within the time value parameters. The injected SPL bypasses the access controls normally enforced by the user's role, allowing the attacker to search and exfiltrate indexed data from across the Splunk instance, including data from security logs, business intelligence, or other sensitive sources they would not ordinarily be permitted to query. |

Alert meAnalysisAIv1 – Aug 19, 2026
SPL injection in Splunk Enterprise exposes all indexed data and compromises search integrity for any low-privileged authenticated user. Specifically, users without the 'admin' or 'power' role can inject Search Processing Language commands into saved-search dispatch requests by supplying malicious time values that Splunk Enterprise fails to validate. Patch versions have been released across all supported branches; no public exploit code or CISA KEV listing has been identified at time of analysis.
RemediationAI
The primary fix is to upgrade Splunk Enterprise to the patched versions released by the vendor: 10.4.2, 10.2.6, 10.0.9, or 9.4.14 depending on the deployed release branch, as detailed in Splunk advisory SVD-2026-0801 (https://advisory.splunk.com/advisories/SVD-2026-0801). If immediate upgrade is not feasible, administrators should consider restricting access to the saved-search dispatch REST API endpoints - for example, by limiting API access to trusted internal networks or requiring elevated role assignment before allowing dispatch operations. Auditing role assignments to minimize the number of accounts without the 'admin' or 'power' role that have REST API access would reduce the attack surface, though this may conflict with broad analyst access requirements. No workaround eliminates the vulnerability without patching; compensating controls should be considered temporary.

Technical ContextAI · show details
Splunk Enterprise uses Search Processing Language (SPL) as its proprietary query language for searching and analyzing machine data indexed across the platform. The flaw is classified as CWE-943 (Improper Neutralization of Special Elements in Data Query Logic), the NoSQL/query injection class, reflecting that SPL - like SQL - is a structured query language susceptible to injection when user input is not properly sanitized before being embedded in queries. The root cause is specifically the absence of correct validation of caller-supplied time parameter values passed to saved-search dispatch REST API endpoints (documented at the Splunk Search Endpoint Descriptions reference). Affected products are identified by CPE cpe:2.3:a:splunk:splunk_enterprise:*:*:*:*:*:*:*:* across the 9.4, 10.0, 10.2, and 10.4 release lines.

Lifecycle Timeline
2DescriptionCVE.org
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could inject Search Processing Language (SPL) into saved-search dispatch requests. This could allow for unauthorized access to all relevant data and affect system integrity within Splunk Enterprise. The vulnerability is possible because Splunk Enterprise does not correctly validate caller-supplied time values before using them in saved-search dispatch. For more information see Search endpoint descriptions (https://help.splunk.com/en/splunk-enterprise/rest-api-reference/10.2/search-endpoints/search-endpoint-descriptions) in the Splunk documentation.
Executive ViewAI
Splunk Enterprise contains a vulnerability (CVSS 8.1) allowing authenticated low-privilege users to inject commands that expose all indexed data and bypass intended access controls. Any user account in your Splunk deployment can access sensitive operational and security data they were not authorized to view, directly compromising data governance and incident response integrity. Immediate patching is required to restore access controls and prevent unauthorized data disclosure.
Apply vendor patch.
