Technical details
The vulnerability is an improper authorization flaw in the sub-workflow task handling mechanism. An authenticated user without permission to access a target project can invoke workflows belonging to that project by referencing them through a sub-workflow task, as the system fails to verify permission before execution. This allows attackers to execute arbitrary workflows and access their associated resources and data.
