Title
Incorrect Authorization in Kibana Leading to Privilege Escalation
Summary
Incorrect Authorization (CWE-863) in Kibana can lead to privilege escalation via Input Data Manipulation (CAPEC-153). Elasticsearch cluster privilege declarations originating from integration packages were not validated before being used to mint credentials for enrolled Elastic Agents. A user holding Fleet management privileges could therefore cause every Elastic Agent on a targeted policy to receive a credential carrying arbitrarily elevated Elasticsearch cluster privileges, up to and including full cluster administration.

Improper Control of Generation of Code in Kibana Leading to Privilege Escalation
Summary
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.

Summary
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.
