CVE-2026-47708
Fix: SepineTam/mcp-for-stata@e6f9459CVE-2026-47708 is a CWE-77 vulnerability in stata-mcp. O3 Security confirms whether CVE-2026-47708 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
MCP-for-Stata: Command injection via log_file_name parameter in Stata command wrapper
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
stata-mcpReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
MCP-for-Stata is an MCP server for Stata to integrate Stata into an agent. Prior to version 1.17.3, the log_file_name parameter in the stata_do 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 shell, python, erase, etc.) by crafting a malicious log_file_name containing quotes, newlines, or Stata command separators. Version 1.17.3 contains a patch for the issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for stata-mcp. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update stata-mcp to 1.17.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-47708 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-47708 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-47708. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-47708 in your dependencies?
O3 detects CVE-2026-47708 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
