No clear supply-chain malware behavior or deliberate obfuscation is evident in the shown fragments. However, the main-process readFile procedure uses a renderer-controlled path directly in fs.promises.readFile with only type-level validation, and error messages/cause propagation embed user-controlled path information. If authorization, path allowlisting, and filesystem confinement are not enforced elsewhere, this design can enable high-impact unintended local file disclosure and information leakage via errors/logs.
