Merged
Conversation
… with PG. These are dangerous to share, and expose things to problems that should not be exposed.
`HTML::Parser` was shared into the safe compartment, and its `parse_file` method opens and reads whatever path it is given, bypassing the permitted_read_dir restriction. Thus giving any PG problem arbitrary file read. It is not actually used by PG, and so that is removed from the modules that are shared. Note that the `HTML::Entities` package which is part of the `HTML::Parser` package on CPAN is still shared and is used.
