CVE-2026-47409: CWE-269: Improper Privilege Management 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 authorization bypass enabling owner lockout. The `DELETE /workspaces/{workspace_id}/members/{user_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`). Any member can remove any other member, including the workspace owner, using a single DELETE. There is no caller-role check, no target-role check, no "cannot remove last owner" guard. PraisonAI Platform version 0.1.4 patches the issue.
AI Analysis
Technical Summary
CVE-2026-47409 describes an improper privilege management vulnerability (CWE-269) in the PraisonAI Platform before version 0.1.4. The DELETE endpoint for removing workspace members is protected only by a minimal role check requiring membership, allowing any member to remove any other member regardless of their role. There are no checks to prevent removing the workspace owner or the last owner, enabling an authorization bypass that can lock out owners from their workspace. This vulnerability is patched in version 0.1.4.
Potential Impact
An attacker with member-level access to a workspace can remove the workspace owner or even the last owner, causing denial of access for legitimate owners. This results in a high impact on integrity and availability of the workspace management, as owners lose control over their workspace membership.
Mitigation Recommendations
Upgrade PraisonAI Platform to version 0.1.4 or later, where this authorization bypass vulnerability is patched. No other mitigations are specified. Patch status is confirmed by the vendor stating version 0.1.4 fixes the issue.
