Hi!
This patch changes
^
and$
operators in regex that validates arguments passed tomattr_reader/writer
methods to\A
and\z
appropriately.Using
^
and$
allows arguments such asvalid\nwhatever_text
that definitely not valid and even more they would be executed in context ofclass_eval
after.So it could lead to the syntax errors or potential code injections if the arguments was created somehow dynamically.
Does it make sense or I miss something?
Thanks and have a good day! ☀️
