PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an Insecure Direct Object Reference. The dependency endpoints ("POST/GET /workspaces/{workspace_id}/issues/{issue_id}/dependencies" and "DELETE .../dependencies/{dep_id}") gate access on "require_workspace_member(workspace_id)" only, then dispatch to "DependencyService" calls that take URL/body-supplied issue and dependency IDs without verifying any of them belong to the membership-checked workspace. Most damaging: "create_dependency" accepts "body.depends_on_issue_id" from the request body — that ID is checked against nothing — letting an attacker create a "blocks" or "related" link between any two issues anywhere in the database. PraisonAI Platform version 0.1.4 patches the issue.
