Nope, no vulnerabilities in Ruby or Python, just PHP. Because PHP sucks, Ruby and Python and Erlang and Go and Java and C++ and blah blah blah blah blah are superior languages to PHP, blah blah blah.
Python 15 in 5 years
Ruby 36 in 7 years
PHP 341 in 14 years
No one claimed that other languages are flawless. Besides that the biggest problem are not vulnerabilities in the languages; the biggest problem are vulnerabilities in products build using the languages and PHP makes it especially hard to write correct code because of its many quirks making it (almost) impossible to be aware of all edge and corner cases.
