Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks." After conducting further research, Mend has determined that all versions of cpython up to version 3.10.6 are vulnerable to CVE-2021-28861.
