PYSEC-2026-544 MCP-for-Stata: Command injection via log_file_name parameter in Stata command wrapper

Summary The logfilename parameter in the statado API and CLI is directly interpolated into a Stata command string without sanitization. The security guard GuardValidator only scans the do-file content but does not validate this parameter. An attacker can inject arbitrary Stata commands including...

CAI find_file Agent Tool has Command Injection Vulnerability Through Argument Injection

SummaryThe CAI Cybersecurity AI framework contains multiple argument injection vulnerabilities in its function tools. User-controlled input is passed directly to shell commands via subprocess.Popen with shell=True, allowing attackers to execute arbitrary commands on the host system. Vulnerable...

utcp-cli Vulnerable to Command Injection via Unsanitized Argument Substitution in CLI Communication Protocol

SummaryThe substituteutcpargs method in clicommunicationprotocol.py inserts user-controlled toolargs values directly into shell command strings without any sanitization or escaping. These commands are then executed via /bin/bash -c Unix or powershell.exe -Command Windows, allowing an attacker to...

PYSEC-2026-473 PraisonAI has an incomplete fix for CVE-2026-34935 - OS Command Injection

Summary The fix for PraisonAI's MCP command handling does not add a command allowlist or argument validation to parsemcpcommand, allowing arbitrary executables like bash, python, or /bin/sh with inline code execution flags to pass through to subprocess execution. Affected Package - Ecosystem: PyP...

PYSEC-2026-407 Marimo: Pre-Auth Remote Code Execution via Terminal WebSocket Authentication Bypass

Summary Marimo 19.6k stars has a Pre-Auth RCE vulnerability. The terminal WebSocket endpoint /terminal/ws lacks authentication validation, allowing an unauthenticated attacker to obtain a full PTY shell and execute arbitrary system commands. Unlike other WebSocket endpoints e.g., /ws that correct...

PYSEC-2026-487 PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)

Summary The memory hooks executor in praisonaiagents passes a user-controlled command string directly to subprocess.run with shell=True at src/praisonai-agents/praisonaiagents/memory/hooks.py lines 303 to 305. No sanitization, no shlex.quote, no character filter, and no allowlist check exists...

PraisonAI Vulnerable to OS Command Injection
