Unsafe evaluation
Proof of concept:
It is never safe to eval() user input, plain and simple. There is always another way to skin the cat; try and consider that!
Mitigation:
Design around combining the function "eval" with user input.
Auditing:
IGNORECASE=1 find -regextype posix-awk -regex ".*\.(rb|php|pl|py|pm)" -exec grep -HnC2 \\beval\( '{}' \;
