CVE-2026-20258 (GCVE-0-2026-20258)

Vulnerability from nvd – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:22

Title

Stored Cross-Site Scripting (XSS) through Classic Dashboard in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.11, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could store a malicious script in a classic dashboard HTML panel, causing unauthorized JavaScript code to execute in the browser of another user. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The low-privileged user should not be able to exploit the vulnerability at will.

CVE-2026-20257 (GCVE-0-2026-20257)

Vulnerability from nvd – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:24

Title

Improper Input Validation through Classic Dashboard CSS in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a classic dashboard that exfiltrates sensitive data from the browser of a higher-privileged user who views it. The exfiltration is possible because classic dashboard panels do not fully validate style attribute values, which can allow for requests to reach external domains outside the configured Trusted Domains List. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The low-privileged user should not be able to exploit the vulnerability at will.

Severity

CVE-2026-20256 (GCVE-0-2026-20256)

Vulnerability from nvd – Published: 2026-06-10 17:15 – Updated: 2026-06-10 18:19

Title

Improper Input Validation through Protocol-Relative URL in Classic Dashboards in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could cause data exfiltration through classic dashboards by redirecting a victim to an external site using a protocol-relative URL in a drill-down link. The vulnerability exists because the URL classifier in classic dashboards only recognizes `http://` and `https://` schemes when checking for external URLs. Protocol-relative URLs such as `//attacker.com` bypass this check entirely, and Splunk Web does not show the external-navigation warning dialog to the victim.

Severity

CVE-2026-20255 (GCVE-0-2026-20255)

Vulnerability from nvd – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:25

Title

Improper Input Validation through Classic Dashboards in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious classic dashboard that exfiltrates sensitive data to an external server. The vulnerability exists because URL validation on the external content dialog is incomplete, which can allow for requests to untrusted domains when a user interacts with a crafted dashboard.

Severity

5.7 (Medium)

CVE-2026-20254 (GCVE-0-2026-20254)

Vulnerability from nvd – Published: 2026-06-10 17:15 – Updated: 2026-06-10 18:27

Title

Information Disclosure through External Content Restriction Bypass in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could craft a malicious classic dashboard that exfiltrates sensitive data to an external server when a higher-privileged user views it, bypassing the external content restriction through a Cascading Style Sheets (CSS) injection. The Trusted Domains security check does not fully validate inline style attribute values, which can allow for outbound requests to untrusted domains and credential exfiltration when a victim views a crafted dashboard.

Severity

5.7 (Medium)

CVE-2026-20253 (GCVE-0-2026-20253)

Vulnerability from nvd – Published: 2026-06-10 17:16 – Updated: 2026-06-11 10:17

Title

Unauthenticated Arbitrary File Creation and Truncation in a PostgreSQL Sidecar Service Endpoint in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4 and 10.0.7, and Splunk Cloud Platform versions below 10.4.2604.3 and 10.2.2510.14, an unauthenticated user could create or truncate arbitrary files through a PostgreSQL sidecar service endpoint. The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials.

Severity

9.8 (Critical)

CVE-2026-20252 (GCVE-0-2026-20252)

Vulnerability from nvd – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:23

Title

Server-Side Request Forgery (SSRF) through Dashboard Studio PDF Export in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.4.2604.3, 10.3.2512.12, 10.2.2510.14, 10.1.2507.22, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could send server-side requests to arbitrary internal destinations through the Dashboard Studio PDF export feature. The vulnerability exists because the trusted-domain validation uses a prefix match that can be bypassed with attacker-controlled subdomains (for example, docs.splunk.com.evil.com), and because the PDF export service follows HTTP redirects automatically without re-validating each redirect target against the allowlist.

Severity

7.6 (High)

CVE-2026-20251 (GCVE-0-2026-20251)

Vulnerability from nvd – Published: 2026-06-10 17:16 – Updated: 2026-06-11 03:55

Title

Remote Code Execution through Deserialization of Untrusted Data in Splunk Secure Gateway

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, Splunk Cloud Platform versions below 10.3.2512.12, 10.2.2510.14, 10.1.2507.22, and 9.3.2411.132, and Splunk Secure Gateway versions below 3.10.6, 3.9.20, and 3.8.67, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could perform a Remote Code Execution (RCE) through the Splunk Secure Gateway app. The Remote Code Execution is possible because of unsafe deserialization of App Key Value Store (KV Store) data through the ‘jsonpickle’ Python library, which reconstructs arbitrary Python objects from specially crafted JavaScript Object Notation (JSON) without adequate validation.

Severity

8.8 (High)

CVE-2026-20240 (GCVE-0-2026-20240)

Vulnerability from nvd – Published: 2026-05-20 16:32 – Updated: 2026-05-20 17:47

Title

Denial of Service through coldToFrozen.sh Script in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.2, 10.0.5, 9.4.11, and 9.3.12, and Splunk Cloud Platform versions below 10.4.2603.1, 10.3.2512.9, 10.2.2510.11, 10.1.2507.21, 10.0.2503.13, and 9.3.2411.129, a low-privileged user that does not hold the ‘admin’ or ‘power’ Splunk roles could cause a Denial of Service by exploiting the `coldToFrozen.sh` script in the `splunk_archiver` app to rename critical Splunk directories, making the instance non-functional. The Denial of Service is possible because of missing input validation in the `coldToFrozen.sh` script, which accepts arbitrary file paths and renames them without restricting operations to safe directories.

Severity

7.1 (High)

CVE-2026-20202 (GCVE-0-2026-20202)

Vulnerability from nvd – Published: 2026-04-15 15:17 – Updated: 2026-04-16 03:55

Title

Improper Input Validation during User Account Creation in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.2, 10.0.5, 9.4.10, and 9.3.11, and Splunk Cloud Platform versions below 10.4.2603.0, 10.3.2512.6, 10.2.2510.10, 10.1.2507.20, 10.0.2503.13, and 9.3.2411.127, a user who holds a role that contains the high-privilege capability `edit_user`could create a specially crafted username that includes a null byte or a non-UTF-8 percent-encoded byte due to improper input validation. This could lead to inconsistent conversion of usernames into a proper format for storage and account management inconsistencies, such as being unable to edit or delete affected users.

Severity

CVE-2026-20258 (GCVE-0-2026-20258)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:22

Title

Stored Cross-Site Scripting (XSS) through Classic Dashboard in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.11, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could store a malicious script in a classic dashboard HTML panel, causing unauthorized JavaScript code to execute in the browser of another user. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The low-privileged user should not be able to exploit the vulnerability at will.

Severity

7.1 (High)

CVE-2026-20253 (GCVE-0-2026-20253)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:16 – Updated: 2026-06-11 10:17

Title

Unauthenticated Arbitrary File Creation and Truncation in a PostgreSQL Sidecar Service Endpoint in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4 and 10.0.7, and Splunk Cloud Platform versions below 10.4.2604.3 and 10.2.2510.14, an unauthenticated user could create or truncate arbitrary files through a PostgreSQL sidecar service endpoint. The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials.

Severity

9.8 (Critical)

CVE-2026-20252 (GCVE-0-2026-20252)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:23

Title

Server-Side Request Forgery (SSRF) through Dashboard Studio PDF Export in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.4.2604.3, 10.3.2512.12, 10.2.2510.14, 10.1.2507.22, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could send server-side requests to arbitrary internal destinations through the Dashboard Studio PDF export feature. The vulnerability exists because the trusted-domain validation uses a prefix match that can be bypassed with attacker-controlled subdomains (for example, docs.splunk.com.evil.com), and because the PDF export service follows HTTP redirects automatically without re-validating each redirect target against the allowlist.

Severity

7.6 (High)

CVE-2026-20257 (GCVE-0-2026-20257)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:24

Title

Improper Input Validation through Classic Dashboard CSS in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a classic dashboard that exfiltrates sensitive data from the browser of a higher-privileged user who views it. The exfiltration is possible because classic dashboard panels do not fully validate style attribute values, which can allow for requests to reach external domains outside the configured Trusted Domains List. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The low-privileged user should not be able to exploit the vulnerability at will.

Severity

5.7 (Medium)

CVE-2026-20255 (GCVE-0-2026-20255)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:16 – Updated: 2026-06-10 18:25

Title

Improper Input Validation through Classic Dashboards in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious classic dashboard that exfiltrates sensitive data to an external server. The vulnerability exists because URL validation on the external content dialog is incomplete, which can allow for requests to untrusted domains when a user interacts with a crafted dashboard.

Severity

5.7 (Medium)

CVE-2026-20251 (GCVE-0-2026-20251)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:16 – Updated: 2026-06-11 03:55

Title

Remote Code Execution through Deserialization of Untrusted Data in Splunk Secure Gateway

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, Splunk Cloud Platform versions below 10.3.2512.12, 10.2.2510.14, 10.1.2507.22, and 9.3.2411.132, and Splunk Secure Gateway versions below 3.10.6, 3.9.20, and 3.8.67, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could perform a Remote Code Execution (RCE) through the Splunk Secure Gateway app. The Remote Code Execution is possible because of unsafe deserialization of App Key Value Store (KV Store) data through the ‘jsonpickle’ Python library, which reconstructs arbitrary Python objects from specially crafted JavaScript Object Notation (JSON) without adequate validation.

Severity

8.8 (High)

Title

Information Disclosure through External Content Restriction Bypass in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could craft a malicious classic dashboard that exfiltrates sensitive data to an external server when a higher-privileged user views it, bypassing the external content restriction through a Cascading Style Sheets (CSS) injection. The Trusted Domains security check does not fully validate inline style attribute values, which can allow for outbound requests to untrusted domains and credential exfiltration when a victim views a crafted dashboard.

Severity

5.7 (Medium)

CVE-2026-20256 (GCVE-0-2026-20256)

Vulnerability from cvelistv5 – Published: 2026-06-10 17:15 – Updated: 2026-06-10 18:19

Title

Improper Input Validation through Protocol-Relative URL in Classic Dashboards in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.3.2512.13, 10.2.2510.15, 10.1.2507.23, and 9.3.2411.132, a low-privileged user that does not hold the 'admin' or 'power' Splunk roles could cause data exfiltration through classic dashboards by redirecting a victim to an external site using a protocol-relative URL in a drill-down link. The vulnerability exists because the URL classifier in classic dashboards only recognizes `http://` and `https://` schemes when checking for external URLs. Protocol-relative URLs such as `//attacker.com` bypass this check entirely, and Splunk Web does not show the external-navigation warning dialog to the victim.

Severity

5.7 (Medium)

CVE-2026-20240 (GCVE-0-2026-20240)

Vulnerability from cvelistv5 – Published: 2026-05-20 16:32 – Updated: 2026-05-20 17:47

Title

Denial of Service through coldToFrozen.sh Script in Splunk Enterprise

Summary

In Splunk Enterprise versions below 10.2.2, 10.0.5, 9.4.11, and 9.3.12, and Splunk Cloud Platform versions below 10.4.2603.1, 10.3.2512.9, 10.2.2510.11, 10.1.2507.21, 10.0.2503.13, and 9.3.2411.129, a low-privileged user that does not hold the ‘admin’ or ‘power’ Splunk roles could cause a Denial of Service by exploiting the `coldToFrozen.sh` script in the `splunk_archiver` app to rename critical Splunk directories, making the instance non-functional. The Denial of Service is possible because of missing input validation in the `coldToFrozen.sh` script, which accepts arbitrary file paths and renames them without restricting operations to safe directories.

Severity

7.1 (High)
