Next Level Smuggling with Web Assembly

1. Update lib.rs with username, password and payload (base64 encoded)

2. Run wasm-pack build --target no-modules --release to compile the library

3. Update the built /pkg/*.js file to replace the __wbg_init function with the code from new_init.js

4. Replace the const base64Wasm = "{{BASE64_ENCODED_WASM}}"; in the new init function with the Base64 encoded /pkg/*.wasm file (you can use base64 -w 0 *.wasm > base64wasm.txt to get the Base64 encoded string)

5. Place the entire updated JavaScript code at the top of the <script> in the template.html file

6. Serve the template.html and try it out!
