Is LeetSync - Leetcode to Github Synchronizer safe?
LeetSync bundles a GitHub OAuth client secret and sends it to GitHub during account authorization.
When you log in with GitHub, the extension exchanges the OAuth code from the browser and includes a bundled client_secret in the request to GitHub's token endpoint. The same secret is shipped in multiple extension scripts, so it is visible in the installed extension package.
