Technical Analysis
This vulnerability in Kibana involves the allocation of resources without proper limits or throttling, classified as CWE-770. An authenticated user with low-level privileges can exploit this by sending a crafted request that triggers excessive memory allocation (CAPEC-130), leading to process termination and denial of service. There is no indication of impact on confidentiality or integrity, only availability is affected. No patch or remediation information is provided, and no known exploits are reported in the wild.
Potential Impact
The impact is a denial of service condition caused by excessive memory consumption in Kibana, which terminates the process and disrupts service availability for all users of the affected instance. There is no reported impact on data confidentiality or integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to authenticated users with low privileges and monitor for unusual memory usage patterns. Avoid deploying vulnerable versions in critical environments if possible.
