What to check
- Applies to
- The 31 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR has published an advisory covering multiple vulnerabilities affecting Splunk Enterprise, Splunk Cloud Platform, and Splunk Universal Forwarder across several version branches. The flaws, disclosed by Splunk in security bulletins SVD-2026-0702 through SVD-2026-0706 (dated 15 July 2026), collectively enable attackers to compromise data confidentiality, data integrity, and to conduct cross-site request forgery (CSRF) attacks against affected instances.
The advisory lists a large number of CVEs spanning the affected product lines, with no single vulnerability singled out as under active exploitation. Affected versions include Splunk Cloud Platform 10.1.2507.x through 10.5.2605.x, Splunk Enterprise 9.3.x through 10.4.x, and Splunk Universal Forwarder 9.4.x through 10.4.x, all below specific patched builds. Organizations running Splunk should consult the vendor bulletins and apply the corresponding patches to remediate the identified issues.
No indicators of compromise, threat actor attribution, or evidence of in-the-wild exploitation are provided in this advisory; it is a vendor patch notification distributed via the French national CERT.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
