OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. The CompiledRule::validateExpression
method evaluates an SpEL expression using an StandardEvaluationContext
, allowing the expression to reach and interact with Java classes such as java.lang.Runtime
, leading to Remote Code Execution. The /api/v1/policies/validation/condition/<expression>
endpoint passes user-controlled data CompiledRule::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. This vulnerability was discovered with the help of CodeQL’s Expression language injection (Spring) query and is also tracked as GHSL-2023-236
. This issue may lead to Remote Code Execution and has been resolved in version 1.2.4. Users are advised to upgrade. There are no known workarounds for this vulnerability.
