CVE-2026-72672: Incorrect Authorization in Kibana Leading to Disclosure of Elastic Defend Endpoint Event Data
- Severity: high (CVSS 7.7 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% 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-863
Description
The Elastic Security capability that suggests existing field values while a user authors endpoint policy artifacts queries Elastic Defend event data with Kibana's internal Elasticsearch account instead of the account of the requesting user. Only Kibana feature privileges are verified, and the caller's Elasticsearch index privileges are not. An authenticated user who holds Elastic Security feature privileges but no read access to the Elastic Defend event indices can therefore retrieve field values from that data, including process command line arguments, which commonly contain tokens, credentials, connection strings, and other sensitive operational detail from protected hosts.
Affected products
- Kibana: from 9.1.0 before 9.4.5 — fixed in 9.4.5
How to fix
Upgrade to a fixed version: Kibana 9.4.5. Check the vendor advisory for mitigations.
