CVE-2026-72669: Missing Authorization in Kibana Leading to Cross-User Information Disclosure and Data Tampering
- Severity: high (CVSS 7.6 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-08-13 · updated 2026-09-04
- Weakness: CWE-862
Description
The state that Kibana stores for an Observability Onboarding flow is not bound to the user who created the flow, and the routes that read and update that state do not verify ownership. An authenticated user who holds only generic read access to the space can therefore discover the onboarding flows of other users, read their onboarding state, and write arbitrary progress data into them. A tampered flow can also cause the owner's onboarding view to fail with a server error.
Affected products
- Kibana: from 8.9.0 before 8.19.19; from 9.0.0 before 9.4.5 — fixed in 8.19.19, 9.4.5
How to fix
Upgrade to a fixed version: Kibana 8.19.19, 9.4.5. Check the vendor advisory for mitigations.
