Last modified

CVE-2026-73081 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. Activepieces is an open source AI workflow automation platform. Prior to 0.80.0, the worker's code-compilation pipeline builds the on-disk path for a Code step from the step's name and passes that path to a shell-invoked build command. EPSS estimates a 0.30% chance of exploitation in the next 30 days.

Description

Activepieces is an open source AI workflow automation platform. Prior to 0.80.0, the worker's code-compilation pipeline builds the on-disk path for a Code step from the step's name and passes that path to a shell-invoked build command. A step name containing shell metacharacters can break out of the intended build invocation and execute arbitrary commands during compilation before any code sandbox is created. An authenticated user with permission to create or edit a flow can execute commands as the worker process user, read and write the worker filesystem, exfiltrate environment secrets, and reach internal services available to the worker. This issue is fixed in version 0.80.0.
