Github CodeQL found potential problems

**Version of emscripten/emsdk:**
2.0.8

The latest version of https://github.com/ffmpegwasm/ffmpeg.wasm-core package is giving some github codeQL potential problem alerts in the generated worker.js file


https://github.com/ente-io/photos-web/pull/1020#pullrequestreview-1373220143

The wasm binary was built using GitHub action
https://github.com/ffmpegwasm/ffmpeg.wasm-core/actions/runs/2856179896

The built binary from the action seems to have expired, but the package publisher has hosted it on
https://unpkg.com/browse/@ffmpeg/core@0.11.0/

Wanted to know, if this is an actual potential problem.

Thanks in Advance!!
