High-risk dynamic loader: this code intentionally executes external Python code from package files, arbitrary local paths, and remote HTTP(S) .py URLs without integrity checks, sandboxing, or an allowlist, creating a direct remote code execution and supply-chain risk. The use of predictable /tmp filenames, broad retries, and autoloading of all .py files in the directory increases attack surface. Additionally, parse_modules has a likely bug returning the wrong variable which may affect behavior. Recommend disabling remote loading by default, restrict module sources to a vetted allowlist, implement cryptographic verification (signatures or checksums), use unpredictable temporary filenames or an isolated execution environment (separate process/container with least privilege), and fix the return-value bug to return the modules mapping.
