CVE-2026-115845An incomplete list of disallowed inputs in the Python code validator of the run_script tool in AWS MCP Server might allow an authenticated remote user to execute arbitrary code... Executive summary A weakness in the Python code validator of the run_script tool in AWS MCP Server could let an authenticated user run arbitrary code inside their own isolated session. The advisory says AWS has already fixed the issue on its side and no customer action is required. Technical summary The flaw is an incomplete list of disallowed inputs in the Python code validator of the run_script sandbox, which is a validation bypass that could allow arbitrary code execution. An authenticated remote user could exploit it with a crafted script, and the advisory says the code would run only within their own isolated session environment. The advisory states the fix was applied service-side. Affected versions are given as N/A because the service is managed and exclusively hosted. No fixed version number is stated because the fix is service-side, and no CVSS score, exploitation status, or detection guidance is stated. Per the advisory, no workaround is needed if run_script is used only to run Python scripts that make AWS API calls. Summaries are generated by AI from the linked advisory text.
