CVE-2025-20227: Information Disclosure through external content warning modal dialog box bypass in Splunk Enterprise Dashboard Studio
Noroxi assessment
Priority: Monitor (action score 17/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.42% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In Splunk Enterprise versions below 9.4.1, 9.3.3, 9.2.5, and 9.1.8, and Splunk Cloud Platform versions below 9.3.2408.107, 9.2.2406.112, 9.2.2403.115, 9.1.2312.208 and 9.1.2308.214, a low-privileged user that does not hold the "admin" or "power" Splunk roles could bypass the external content warning modal dialog box in Dashboard Studio dashboards which could lead to an information disclosure.
