CVE-2021-26253splunksplunk+1
EPSS score0.82%
A potential vulnerability in Splunk Enterprise's implementation of DUO MFA allows for bypassing the MFA verification in Splunk Enterprise versions before 8.1.6. The potential vulnerability impacts Splunk Enterprise instances configured to use DUO MFA and does not impact or affect a DUO product or service.CVE-2021-42743splunksplunk+1EPSS score0.23%
A misconfiguration in the node default path allows for local privilege escalation from a lower privileged user to the Splunk user in Splunk Enterprise versions before 8.1.1 on Windows.CVE-2021-31559splunksplunk+1EPSS score0.89%
A crafted request bypasses S2S TCP Token authentication writing arbitrary events to an index in Splunk Enterprise Indexer 8.1 versions before 8.1.5 and 8.2 versions before 8.2.1. The vulnerability impacts Indexers configured to use TCPTokens. It does not impact Universal Forwarders.CVE-2021-3422splunksplunk+1EPSS score0.60%
The lack of validation of a key-value field in the Splunk-to-Splunk protocol results in a denial-of-service in Splunk Enterprise instances configured to index Universal Forwarder traffic. The vulnerability impacts Splunk Enterprise versions before 7.3.9, 8.0 versions before 8.0.9, and 8.1 versions before 8.1.3. It does not impact Universal Forwarders. When Splunk forwarding is secured using TLS or a Token, the attack requires compromising the certificate or token, or both. Implementation of either or both reduces the severity to Medium.CVE-2021-33845splunksplunk+1EPSS score0.90%
The Splunk Enterprise REST API allows enumeration of usernames via the lockout error message. The potential vulnerability impacts Splunk Enterprise instances before 8.1.7 when configured to repress verbose login errors.CVE-2025-20366splunksplunk+2EPSS score0.44%
In Splunk Enterprise versions below 9.4.4, 9.3.6, and 9.2.8, and Splunk Cloud Platform versions below 9.3.2411.111, 9.3.2408.119, and 9.2.2406.122, a low-privileged user that does not hold the admin or power Splunk roles could access sensitive search results if Splunk Enterprise runs an administrative search job in the background. If the low privileged user guesses the search job’s unique Search ID (SID), the user could retrieve the results of that job, potentially exposing sensitive search results.

The authenticated user should not be able to exploit the vulnerability at will.CVE-2025-20379splunksplunk+2EPSS score0.30%
In Splunk Enterprise versions below 10.0.1, 9.4.5, 9.3.7, and 9.2.9 and Splunk Cloud Platform versions below 9.3.2411.116, 9.3.2408.124, 10.0.2503.5 and 10.1.2507.1, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could run a saved search with a risky command using the permissions of a higher-privileged user to bypass the SPL safeguards for risky commands.

The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.CVE-2025-20320splunksplunk+3EPSS score0.46%
In Splunk Enterprise versions below 9.4.3, 9.3.5, 9.2.7 and 9.1.10, and Splunk Cloud Platform versions below 9.3.2411.107, 9.3.2408.117, and 9.2.2406.121, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload through the `User Interface - Views` configuration page that could potentially lead to a denial of service (DoS).The user could cause the DoS by exploiting a path traversal vulnerability that allows for deletion of arbitrary files within a Splunk directory. The vulnerability requires the low-privileged user to phish the administrator-level 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-2025-20319splunksplunk+1EPSS score0.53%
