# CVE-2026-40149

## Summary

- **CVE ID:** CVE-2026-40149
- **Severity:** HIGH
- **CVSS Score:** 7.9 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:N)
- **CWE:** CWE-396
- **Published:** Apr 9, 2026
- **Last Modified:** Apr 13, 2026

## Description

PraisonAI is a multi-agent teams system. Prior to 4.5.128, the gateway's /api/approval/allow-list endpoint permits unauthenticated modification of the tool approval allowlist when no auth_token is configured (the default). By adding dangerous tool names (e.g., shell_exec, file_write) to the allowlist, an attacker can cause the ExecApprovalManager to auto-approve all future agent invocations of those tools, bypassing the human-in-the-loop safety mechanism that the approval system is specifically designed to enforce. This vulnerability is fixed in 4.5.128.
