Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection in the rules engine process. An attacker can execute arbitrary code on the server, read arbitrary files, steal environment variables including database credentials, and bypass multi-tenant isolation to access data across all realms by creating malicious JavaScript rulesets with the write:rules role due to insufficient sandboxing and authorization checks.
