CVE-2026-76288
CVE-2026-76288 updated by NVD
Summary
In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, an unauthenticated user could send a single crafted request to the Splunk Web JavaScript logger endpoint and cause Splunk Web to stop responding to requests. Splunk Web remains unavailable until Splunk Enterprise is restarted. The vulnerability is possible because Splunk Web does not limit request-header parsing before processing the request.
