# CVE-2026-47417: praisonai-platform: Comment endpoints accept any issue\_id without workspace ownership check, cross-workspace comment read and post IDOR

- Also known as: PYSEC-2026-2933, GHSA-CP4F-5M9R-5JC2
- Severity: CVSS 8.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 0.1.4
- Published: 2026-07-21 · Updated: 2026-07-21

## Affected

- MervinPraison praisonai-platform: fixed in 0.1.4
- praisonai-platform (PyPI): fixed in 0.1.4

## Description

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.

## What to do

- Check your stack: if you ship or depend on MervinPraison praisonai-platform, praisonai-platform, upgrade to a fixed version (0.1.4) per the references below.
