CVE-2026-72669
HighCVSS 7.6Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
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 with only generic read access to the space can discover other users' onboarding flows, read their state, and write arbitrary progress data. A tampered flow can also cause the owner's onboarding view to fail with a server error.
Risk Assessment
An attacker could manipulate other users' data, potentially leading to disruption and information leakage.
Recommendation
Apply security patches provided by Elastic for Kibana.
Original NVD description (English source)
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.
