Overview
Affected versions of this package are vulnerable to Execution with Unnecessary Privileges through the run_script.py and run_script.rb script execution paths in the script runner components. An attacker can read sensitive credentials by running a script that prints the process environment, exposing Redis, API, service, TSDB, and bucket secrets to anyone who can view the script output. This leaks authentication material from the running script process and can let an attacker reuse those credentials to access backend services and data.
