CVE-2026-47413 MervinPraison CVE debrief

Who should care

Users of PraisonAI Platform versions prior to 0.1.4 should be aware of this critical vulnerability and take immediate action to patch their systems. This vulnerability has a CVSS score of 9.6 and is considered critical. Operators, platform administrators, vulnerability management teams, and security teams should review the affected scope and severity with the vendor and plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Technical summary

The vulnerability exists in the `POST /workspaces/{workspace_id}/members` endpoint of PraisonAI Platform. The endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role='member'`) and forwards the request body's `user_id` and `role` straight into `MemberService.add(workspace_id, user_id, role)`, which has no caller-permission check. This allows for privilege escalation and cross-tenant member injection. The vulnerability has a CVSS score of 9.6 and is considered critical.

Defensive priority

High

Recommended defensive actions

• Patch PraisonAI Platform to version 0.1.4 or later
• Restrict access to the `POST /workspaces/{workspace_id}/members` endpoint
• Monitor for suspicious activity on the PraisonAI Platform
• Implement additional security measures to prevent privilege escalation and cross-tenant member injection
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
