The codebase consists of auto-generated API client libraries (C++, Java, Kotlin, Angular, Perl, C#, Go, Dart, JavaScript, PHP, Haskell, Rust, Elixir, Lua, Python) using standard HTTP and JSON parsing libraries. URL encoding for parameters is consistently applied (`QUrl::toPercentEncoding`, `URLEncoder.encode`), which is good for preventing URL injection. API keys and other credentials are handled via programmatic setting, with examples showing placeholder values. There are no obvious hardcoded production secrets or malicious patterns (like `eval` on untrusted input). A potential, non-critical risk exists if downloaded filenames derived from `Content-Disposition` headers are not thoroughly sanitized before being used to write files to the local disk, which could lead to path traversal vulnerabilities in the consuming application. The C++ OAuth `ReplyServer` binds to a local port (9999) and sends static HTML, which is generally acceptable for local development and redirect handling.
