CVE-2025-20385: Stored Cross-Site scripting (XSS) through Anchor Tag "href" in Navigation Bar Collections in Splunk Enterprise
Noroxi assessment
Priority: Monitor (action score 19/100)
- 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: 0.29% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
- Severity is disputed: the assigning authority (CNA) scores it 2.4, NVD 4.8.
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 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and Splunk Cloud Platform versions below 10.1.2507.6, 10.0.2503.7, and 9.3.2411.117, a user who holds a role with a high privilege capability `admin_all_objects` could craft a malicious payload through the href attribute of an anchor tag within a collection in the navigation bar, which could result in execution of unauthorized JavaScript code in the browser of a user.
