CVE-2026-47406: CWE-639: Authorization Bypass Through User-Controlled Key in MervinPraison praisonai-platform
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.
AI Analysis
Technical Summary
CVE-2026-47406 describes an Insecure Direct Object Reference vulnerability in PraisonAI Platform versions before 0.1.4. The affected endpoints (/workspaces/{workspace_id}/issues/{issue_id}/dependencies and DELETE /dependencies/{dep_id}) only check if the user is a member of the specified workspace but do not verify that the issue or dependency IDs provided in the URL or request body belong to that workspace. This flaw allows an attacker with legitimate workspace membership to create or delete dependency links between any issues in the database, bypassing intended authorization boundaries. The vulnerability is fixed in version 0.1.4.
Potential Impact
An attacker with at least limited privileges in a workspace can manipulate issue dependencies across all workspaces, potentially linking unrelated or unauthorized issues. This can lead to unauthorized data relationships and integrity issues. The vulnerability has high confidentiality and integrity impact but does not affect availability.
Mitigation Recommendations
Upgrade PraisonAI Platform to version 0.1.4 or later, where the issue is patched. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in the advisory, but the description states version 0.1.4 patches the issue, indicating an official fix is available.
