Terry J. Reedy added the comment: We all know that blindly inserting external data into a database can be a bad idea. But raising ValueError if the data contains \n barely scratches the surface of a real defense. The external data should be checked before passing it to .add_section or as part of a derived method in a subclass. I already suggested the possibility of allowing only a restricted set of letter characters. Such a check comes after defending against the possibility of someone submitting 'a'*1000000 as, in this case, a section name.
configparser is permissive by design, not by accident. The un-abbreviated verbose re for ConfigParser.SECTCRE say so. (?P<header>[^]]+) # very permissive! ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25723> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
