# Kibana: connector logs leak across spaces to users with read access

An authenticated Kibana user with read access to connectors in one space can view connector execution logs from other spaces they should not reach. The exposed data includes connector names and IDs, execution status, timestamps, error messages, and aggregate execution statistics.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with read access to connectors in one Kibana space can retrieve connector execution log information from other spaces that they are not authorized to access. The disclosed information includes connector names and identifiers, execution status, timestamps, error messages, and aggregated execution statistics.
