Description
Nagios XI versions prior to 5.8.7 used a temporary directory for Highcharts exports with overly permissive ownership/permissions under the Apache user. Local or co-hosted processes could read/overwrite export artifacts or manipulate paths, risking disclosure or tampering and potential code execution depending on deployment.
