CVE-2024-28254

OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. The `‎AlertUtil::validateExpression` method evaluates an SpEL expression using `getValue` which by default uses the `StandardEvaluationContext`, allowing the expression to reach and interact with Java classes such as `java.lang.Runtime`, leading to Remote Code Execution. The `/api/v1/events/subscriptions/validation/condition/<expression>` endpoint passes user-controlled data `AlertUtil::validateExpession` allowing authenticated (non-admin) users to execute arbitrary system commands on the underlaying operating system. In addition, there is a missing authorization check since `Authorizer.authorize()` is never called in the affected path and, therefore, any authenticated non-admin user is able to trigger this endpoint and evaluate arbitrary SpEL expressions leading to arbitrary command execution.
