Technical description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user could inject arbitrary Search Processing Language (SPL) into requests that search for events near a selected event. This could allow for unauthorized search execution. The vulnerability is possible because Splunk Web does not consistently escape caller-supplied values when it builds SPL for nearby-event searches, and embedded report access accepts those requests without the expected authorization check. For more information see Use time to find nearby events (https://help.splunk.com/en/splunk-enterprise/search/search-manual/10.2/specify-time-ranges/use-time-to-find-nearby-events) in the Splunk documentation.

——0A vulnerability was identified in chenhg5 cc-connect up to 1.4.1. This affects the function shellExecCommand of the file core/engine.go of the component Management API. Such manipulation of the argument exec leads to os command injection. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The reported GitHub issue was closed automatically due to inactivity.18h CVE-2026-765917.4 HIG

——0In 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 arbitrary Search Processing Language (SPL) commands through the geostats command. The injected SPL runs with the permissions of another authenticated user after that user initiates the attacker-controlled geostats search in Splunk Web. The injected SPL could expose all relevant data available to the second user, including stored credentials, and modify lookup files that the second user has permission to change. The vulnerability is possible because the geostats command does not sufficiently validate input before Splunk Enterprise processes it. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who does not hold the "admin" or "power" Splunk roles should not be able to exploit the vulnerability at will. For more information see geostats (https://help.splunk.com/en/splunk-enterprise/spl-search-reference/10.0/search-commands/geostats) in the Splunk documentation.19h CVE-2026-763286.7 MED

——0In Splunk Enterprise versions below 10.4.1, 10.2.6, 10.0.9, and 9.4.14, a user who holds the "power" Splunk role could store attacker-controlled Search Processing Language (SPL) in a dashboard. When another authenticated user exports the dashboard as a Portable Document Format (PDF) file, Splunk Enterprise runs the injected SPL using the permissions of that user. The injected SPL could access or modify data available to that user. The vulnerability is possible because Splunk Web does not sufficiently validate dashboard content before processing PDF exports. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the "power" Splunk role should not be able to exploit the vulnerability at will. For more information see Generate PDFs of your reports and dashboards (https://help.splunk.com/en/splunk-enterprise/create-dashboards-and-reports/reporting-manual/9.4/report-management/generate-pdfs-of-your-reports-and-dashboards) in the Splunk documentation.19h CVE-2026-765837.4 HIG
