CVE-2026-82298

Kibana versions prior to 5.2.1 configured for SSL client access do not clean up file descriptors after certain requests, leading to accumulation over time until the process crashes.

Kibana versions before 4.5.4 and 4.1.11, when a custom output is configured for logging, may write cookies and authorization headers to log files. This information could be used to hijack sessions of other users using Kibana behind some form of authentication such as Shield.

Incorrect Authorization in Kibana can lead to unauthorized configuration modification via exploiting incorrectly configured access control security levels.

Incorrect Authorization (CWE-863) in Kibana can lead to information disclosure via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180).

Missing Authorization in Kibana Leading to Unauthorized Modification of Data / Missing Authorization (CWE-862) in Kibana can lead to unauthorized modification of data via Privilege Abuse (CAPEC-122). An authenticated user holding Security read-level access in a single Kibana space could trigger Entity Analytics migration operations that perform privileged writes across all Kibana spaces, regardless of that user's actual access scope.

Missing Authorization in Kibana Leading to Information Disclosure / Missing Authorization (CWE-862) in the Kibana Fleet feature can lead to information disclosure via Privilege Abuse (CAPEC-122). An authenticated user holding read-level Fleet agent privileges in one Kibana space could enumerate agent metadata and access diagnostic content belonging to agents enrolled in other Kibana spaces.

An insufficiently validated configuration field in Kibana's Cribl integration allows an authenticated user holding Kibana Fleet management privileges to inject attacker-controlled expressions into a server-side script template, resulting in an Elasticsearch ingest pipeline being written beyond the caller's authorized Elasticsearch permissions.

Incorrect Authorization in Kibana can lead to privilege escalation via input data manipulation. Elasticsearch cluster privilege declarations from integration packages were not validated before being used to mint credentials for enrolled Elastic Agents.

Incorrect Authorization (CWE-863) in the Kibana machine learning feature can lead to unauthorized resource consumption via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). An authenticated user could invoke machine learning functionality beyond their authorization scope, consuming cluster resources they should not be able to reach.
