CVE-2026-57137 PUBLISHED

PraisonAI AgentLoop onToolCall approval runs after tool execution

Assigner: GitHub_M
Reserved: 24.06.2026 Published: 15.09.2026 Updated: 15.09.2026

PraisonAI is a multi-agent teams system. From 1.4.0 until 1.7.2, createAgentLoop() in src/praisonai-ts/src/ai/agent-loop.ts passes executable tools to generateText() before invoking the onToolCall approval callback. Because the wrapped AI SDK executes tool handlers during generation, a callback that returns false records tool_rejected only after the denied tool has already produced side effects and populated toolResults. Applications using onToolCall as a human or policy approval boundary can therefore execute rejected file, command, API, or data-modifying operations. This issue is fixed in version 1.7.2.
