See https://github.com/Pylons/waitress/pull/370 #### 2.1.2 ## Bugfix ## Security Fixes - In Waitress version 1.4.2 a new regular expression was added to validate the headers that Waitress receives to make sure that it matches RFC7230. Unfortunately the regular expression #### 1.4.1 (2019-12-24) ## Security Fixes - Waitress did not properly validate that the HTTP headers it received were properly formed, thereby potentially allowing a front-end server to treat a request
