CVE-2026-72673— Incorrect Authorization in Kibana Leading to Unauthorized Deletion of Synthetics Private Locations

Quick assessment

Affected
Elastic Kibana
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elastic Kibana是荷兰Elastic公司开源的一个视觉化仪表板。 Elastic Kibana 8.0.0至8.19.19版本和9.0.0至9.4.3版本存在授权问题漏洞，该漏洞源于授权不正确，通过访问功能未受ACL适当限制，删除Synthetics私有位置时未评估其他空间中的相关监控，可能导致经身份验证的用户删除其他空间仍依赖的私有位置，从而停止监控并影响可用性。

Vulnerability Title
Incorrect Authorization in Kibana Leading to Unauthorized Deletion of Synthetics Private Locations
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect Authorization (CWE-863) in Kibana can lead to unauthorized deletion of Synthetics private locations via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). Synthetics private locations can be shared with more than one space, and deleting one removes it from every space it is shared with. The safeguard that prevented the deletion of a private location still in use evaluated only the monitors visible in the requesting user's own space, so monitors that depend on the private location in other spaces were not taken into account. As a result, an authenticated Kibana user holding the Synthetics write privilege in a single space could delete a private location that other spaces still depend on, even where the user has no access to those spaces. Deleting the private location removes the shared configuration and stops the monitors in the other spaces from running, which suppresses the availability monitoring those spaces rely on.
