AI-suggested
A patch is available in Orkes Conductor version 3.30.2. Users should upgrade to this version or later to remediate the vulnerability. Since this is an unauthenticated remote code execution flaw, applying the official fix is critical. No alternative mitigations or workarounds are indicated in the vendor advisory.
Description
Orkes Conductor versions 3.21.21 up to but not including 3.30.2 contain a critical unauthenticated remote code execution vulnerability. This flaw allows remote attackers to execute arbitrary operating system commands by submitting malicious inline workflow definitions with JavaScript or Python expressions to the workflow API endpoint before authentication. The vulnerability arises from unsandboxed GraalVM evaluators configured with permissive HostAccess settings, enabling invocation of system commands via Java reflection or subprocess calls. A fix is available in version 3.30.2.
