Authenticated code execution via crafted Code step name
Published Aug 11, 2026 · Updated Aug 11, 2026
OS command injection in Activepieces before 0.80.0 allows remote authenticated users to execute commands through a crafted Code step name. The worker derives the Code step path from a name accepted as any string, then places that path in a build command run through /bin/sh, allowing shell metacharacters to alter the command. Flow create or edit permission is required; execution occurs as the worker process user before sandbox creation and exposes its files, secrets, and reachable internal services.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
