Last modified
CVE-2026-25904 is a medium-severity vulnerability rated 5.8/10 on the CVSS scale. The Pydantic-AI MCP Run Python tool configures the Deno sandbox with an overly permissive configuration that allows the underlying Python code to access the localhost interface of the host to perform SSRF attacks. Note - the "mcp-run-python" project is archived and unlikely to receive a fix.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
