CVE-2026-47418 MervinPraison CVE debrief

CVE-2026-47418 is an Insecure Direct Object Reference vulnerability in PraisonAI Platform versions prior to 0.1.4. The project CRUD endpoints gate access on workspace membership only, then resolve project IDs without constraining lookups by workspace ID. This allows a user who is a member of any workspace W1 to read, modify, delete, or read stats for projects that belong to a different workspace W2. The vulnerability has a high impact on system security and integrity.

Who should care

Defenders of PraisonAI Platform, users of versions prior to 0.1.4, and security teams responsible for vulnerability management should be aware of this vulnerability and take immediate action to patch or mitigate. This includes reviewing system deployments, assessing exposure, and implementing compensating controls where necessary.

Technical summary

The PraisonAI Platform has an Insecure Direct Object Reference vulnerability in versions prior to 0.1.4. The project CRUD endpoints (GET / PATCH / DELETE /workspaces/{workspace_id}/projects/{project_id} and GET .../{project_id}/stats) only gate access based on workspace membership (require_workspace_member(workspace_id)), but then resolve project IDs through ProjectService.get(project_id) / update(project_id, ...) / delete(project_id) / get_stats(project_id) without threading workspace_id to constrain the lookup.

Defensive priority

High

Recommended defensive actions

  • Patch PraisonAI Platform to version 0.1.4 or later
  • Restrict access to project endpoints based on workspace membership and project ownership
  • Monitor project endpoints for suspicious activity
  • Implement additional access controls to prevent unauthorized project access
  • Review system deployments for exposure and assign an owner for follow-up
  • Confirm whether affected product deployments exist in managed environments
  • Track exceptions and retest remediated assets
