CVE-2026-40149
7.9 · HIGHOverview
CVE-2026-40149 is a high-severity vulnerability affecting praison praisonai. It was published on April 9, 2026 and has a CVSS 3.1 base score of 7.9 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.9, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from praison. Update praisonai to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
