Hi, The following vulnerability was published for waitress. CVE-2022-31015[0]: | Waitress is a Web Server Gateway Interface server for Python 2 and 3. | Waitress versions 2.1.0 and 2.1.1 may terminate early due to a thread | closing a socket while the main thread is about to call select(). This | will lead to the main thread raising an exception that is not handled | and then causing the entire application to be killed. This issue has | been fixed in Waitress 2.1.2 by no longer allowing the WSGI thread to | close the socket. Instead, that is always delegated to the main | thread. There is no work-around for this issue. However, users using | waitress behind a reverse proxy server are less likely to have issues | if the reverse proxy always reads the full response. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
