Upgrade github.com/shareup/wasm-interpreter-apple to Latest secure release
pywasm3 fixed: Latest secure release 
pip install pywasm3>=Latest secure release
wasm3 fixed: Latest secure release 
Upgrade wasm3 to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/shareup/wasm-interpreter-apple

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-27529, inspect your project dependencies for Github.com/shareup/wasm interpreter apple:

inspect dependencies for github.com/shareup/wasm-interpreter-apple
