Title
Insertion of Sensitive Information into Log File in Kibana Leading to Information Disclosure
Summary
Insertion of Sensitive Information into Log File (CWE-532) in Kibana can lead to information disclosure. When the optional application performance monitoring (APM) instrumentation is enabled, sensitive request header values could be recorded in application logs, where they may be accessible to operators with log access.
