Thanks for the report,
Yes, this is caused by a recent git security update as described here:
https://github.blog/2022-04-12-git-security-vulnerability-announced/
https://git-scm.com/docs/git-config/2.35.2#Documentation/git-config.txt-safedirectory

This can be mitigated in two ways:

1. the docker image is using root user, to make git happy
   run chown -R root:root . in the checked out proxysql_mysqlbinlog folder
2. add the config option safe.directory = * to .git/config,
   run git config --global --add safe.directory * in the checked out proxysql_mysqlbinlog folder

I will update the docker image entrypoint to set the safe.directory accordingly.
