AI-Generated

Kibana is vulnerable to a denial of service attack due to uncontrolled resource consumption, allowing an authenticated low-privilege attacker to send oversized request payloads that exhaust heap memory. This can lead to the application crashing and becoming unavailable to all users. Organizations using Kibana, particularly those with user authentication mechanisms in place, should prioritize addressing this vulnerability to maintain service availability.

Original NVD Description

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated attacker with low-privilege access can trigger a denial of service condition in Kibana by sending a specially crafted, oversized request payload. Processing this user-supplied input requires resource-intensive memory allocation that can exhaust the available heap memory in the Kibana process, causing it to crash and become unavailable to all users.
