photons

The 'math.photon.ts' file uses 'new Function()' to evaluate mathematical expressions (`new Function(...Object.keys(allowed), `return (${expr})`)`). If the 'expression' parameter is supplied by an untrusted source (like an AI, which should always be considered untrusted), this allows for arbitrary code execution with the permissions of the running Photon server. This is a critical security vulnerability. Other photons implement good practices like path validation for filesystem operations and rely on environment variables for sensitive credentials, which is generally secure. However, the presence of 'new Function' makes the overall collection unsafe if the 'math' photon is exposed to untrusted input.
