JLSEC-2026-107 Deno permission escalation vulnerability via open of privileged files with missing `--deny` flag

The Deno sandbox may be unexpectedly weakened by allowing file read/write access to privileged files in various locations on Unix and Windows platforms. For example, reading /proc/self/environ may provide access equivalent to --allow-env, and writing /proc/self/mem may provide access equivalent t...

CVE-2026-25904

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...

Server-side Request Forgery (SSRF)

Overview mcp-run-python is a Model Context Protocol server to run Python code in a sandbox. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF due to an overly permissive configuration of the Deno sandbox, which allows access to the localhost interface. An attack...
