Overview
github.com/elastic/beats/v7/libbeat/processors/script/javascript is a lightweight shippers for Elasticsearch & Logstash
Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File due to improper logging of sensitive information when handling failed event ingestions to Elasticsearch with certain HTTP status codes. An attacker can gain access to sensitive or private information by inducing the application to log events at the WARN or ERROR level.
Note: This vulnerability affects only the Beats application and Elastic Agent, when logging data from the Javascript runtime.
Workaround
This log line is logged at the WARN level; changing the log level to ERROR will suppress these logs. For Beats and standalone Elastic Agent the log level can be changed in the configuration file, see:
