Kibana 8.19.x < 8.19.21 / 9.0.x < 9.4.6 / 9.5.x < 9.5.2 DoS (ESA-2026-125)

medium Nessus Plugin ID 344308

Synopsis

The remote host is affected by a denial of service vulnerability.

Description

The version of Kibana installed on the remote host is 8.19.x prior to 8.19.21, or 9.0.x prior to 9.4.6, or 9.5.x prior to 9.5.2. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-125 advisory.

 - Improper Handling of Highly Compressed Data (CWE-409) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user holding Streams management privileges could supply specially crafted content that expands to a far larger volume of data during processing, exhausting the memory available to Kibana. The Kibana process is terminated by the host and remains unavailable to all users until the service is restarted. (CVE-2026-72628)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update to Kibana version 8.19.21, 9.4.6, 9.5.2 or later.
