CVE-2026-47405 in PraisonAI
Summary
by MITRE • 07/21/2026
PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have a broken workspace authorization check that allows any authenticated low-privilege workspace member to escalate their own role to `owner`. The issue is caused by privileged workspace-management routes using the shared dependency `require_workspace_member(...)` without requiring `admin` or `owner`. The dependency defaults to `min_role="member"`, so routes that should be administrative are accessible to ordinary workspace members. As a result, a normal workspace member can promote their own account from `member` to `owner`; add arbitrary users as `owner` or `admin`; change other members' roles; remove legitimate owners or members; take over workspace membership completely; and/or perform destructive workspace operations after escalation. This is a broken access control / vertical privilege escalation vulnerability. PraisonAI Platform version 0.1.4 patches the issue.

Analysis

The PraisonAI Platform vulnerability represents a critical access control failure that undermines the security foundation of the multi-agent teams system. This issue affects versions prior to 014 and demonstrates a fundamental flaw in the platform's authorization mechanisms. The vulnerability stems from improper role validation within the workspace management functionality, where administrative operations are incorrectly exposed to users with minimal privileges. The core technical problem lies in how the shared dependency `require_workspace_member(...)` is implemented and utilized across different routes. This dependency serves as a gateway mechanism but fails to enforce proper privilege levels for sensitive operations. When routes that should require elevated permissions like `admin` or `owner` rely on a function that defaults to `min_role="member"`, it creates an exploitable condition where ordinary users can gain unauthorized access to administrative controls.
The operational impact of this vulnerability is severe and far-reaching within the PraisonAI ecosystem. An authenticated user with basic member privileges can execute a series of destructive operations that fundamentally compromise workspace integrity and security. The escalation path allows for complete takeover of workspace membership management, enabling attackers to elevate their own status from member to owner, which grants them unrestricted control over the entire workspace environment. Beyond simple privilege escalation, malicious actors can add arbitrary users with elevated roles, modify existing member permissions, remove legitimate owners or administrators, and ultimately assume complete administrative control. This type of vertical privilege escalation directly violates the principle of least privilege and creates a pathway for persistent unauthorized access to sensitive workspace data and configurations.
This vulnerability aligns with several established cybersecurity frameworks and threat models. From a CWE perspective, this represents a classic case of improper access control classified under CWE-284, which specifically addresses "Improper Access Control" in software systems. The issue also maps to ATT&CK technique T1078.004, "Valid Accounts: Cloud Accounts," as it exploits legitimate authentication mechanisms to gain elevated privileges within the platform. Additionally, this vulnerability demonstrates characteristics of privilege escalation patterns commonly found in broken access control scenarios, where insufficient authorization checks allow users to perform actions beyond their intended role boundaries. The fact that this issue affects a shared dependency across multiple routes suggests a systemic architectural problem rather than an isolated bug.
The mitigation strategy for this vulnerability requires immediate patching to version 014 or later, which implements proper role validation mechanisms. Organizations using affected versions should conduct comprehensive security audits of their workspace configurations and monitor for unauthorized privilege changes. System administrators should review existing user roles and permissions to identify any potential compromise from this vulnerability. The fix implemented in version 0.1.4 addresses the root cause by ensuring that administrative routes require appropriate authorization levels before executing sensitive operations. This remediation approach aligns with security best practices for access control implementation, where privilege boundaries are strictly enforced through proper authentication and authorization checks rather than relying on default configurations that may inadvertently expose elevated functionality to unauthorized users.
