csrf-lite is a CSRF protection utility for framework-free node sites.
Affected versions of the package are vulnerable to a timing attack.
While the CSRF protection itself works well and increases security, the library uses the built-in string comparison mechanism,
===, and not a time constant string comparison. As a result, the comparison will fail faster when the first characters in the token are incorrect.
An attacker can use this difference to perform a timing attack, essentially allowing them to guess the CSRF token one character at a time.
