CVE-2026-47708 SepineTam CVE debrief

Who should care

Users of MCP-for-Stata versions prior to 1.17.3 should apply the patch to prevent arbitrary command injection. This vulnerability is particularly concerning for environments where Stata is integrated into larger systems or used by multiple users.

Technical summary

The `log_file_name` parameter in MCP-for-Stata's `stata_do` API and CLI is directly interpolated into a Stata command string without proper sanitization. The security guard, `GuardValidator`, only scans do-file content and does not validate this parameter. An attacker can inject arbitrary Stata commands by crafting a malicious `log_file_name` containing quotes, newlines, or Stata command separators. The vulnerability is patched in version 1.17.3.

Defensive priority

High priority should be given to updating MCP-for-Stata to version 1.17.3 or later. In the meantime, validate and sanitize all user input for the `log_file_name` parameter. Monitor system logs for suspicious Stata command activity.

Recommended defensive actions

• Update MCP-for-Stata to version 1.17.3 or later
• Validate and sanitize all user input for the `log_file_name` parameter
• Monitor system logs for suspicious Stata command activity
• Implement additional security measures to restrict Stata command execution
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
