🚨 Severity: CRITICAL
💡 Vulnerability: Shell command execution and external network requests lacked explicit timeout boundaries and buffer limits, allowing potentially hanging commands or massive outputs to cause Denial of Service (DoS) through resource exhaustion.
🎯 Impact: Malicious or runaway agent actions could exhaust system memory or block execution threads indefinitely.
🔧 Fix: Added strict boundary limits by explicitly passing
timeout: 30000andmaxBuffer: 2 * 1024 * 1024options for process execution, and a 30s timeout for network requests.✅ Verification: Verified by compiling via
npm run buildand runningnpm run test, ensuring no regressions. Tests passed and test artifact was removed.PR created automatically by Jules for task 8614635934782687310 started by @thirdbase1
