🚨 Severity: MEDIUM
💡 Vulnerability: Autonomous agent operations via
ShellToolandAgentConnectorlacked timeouts and max buffer limits. This could allow an agent to hang the system indefinitely or exhaust system resources (e.g., waiting for interactive input, or receiving massive amounts of output) leading to a Denial of Service (DoS).🎯 Impact: Potential host resource exhaustion and DoS, causing the agent loop to crash or block indefinitely.
🔧 Fix: Implemented strict boundaries:
ShellTool: Added a 30-second execution timeout and a 5MB maximum output buffer toexecAsync.AgentConnector: Added a 30-second network timeout to the Axios client configuration.✅ Verification: Verified that build (
npm run build) and tests (npm run test) continue to pass successfully. Documented learnings in.jules/sentinel.md.PR created automatically by Jules for task 1629915704980769719 started by @thirdbase1
