CVE-2026-47417

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 comment endpoints (`POST /workspaces/{workspace_id}/issues/{issue_id}/comments` and `GET .../comments`) gate access on `require_workspace_member(workspace_id)` only, then call `CommentService.create(issue_id=issue_id, ...)` and `CommentService.list_for_issue(issue_id)` without verifying that `issue_id` belongs to `workspace_id`. A user who is a member of any workspace `W1` can read every comment on, and post new comments to, any issue in any other workspace `W2`. PraisonAI Platform version 0.1.4 patches the issue.
