Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).

Test if a finite double-precision floating-point number is a negative integer.
Test if a finite double-precision floating-point number is a negative integer.
npm install @stdlib/math-base-assert-is-negative-integer
var isNegativeInteger = require( '@stdlib/math-base-assert-is-negative-integer' );
Tests if a finite double-precision floating-point number is a negative integer
.
var bool = isNegativeInteger( -1.0 );
// returns true
bool = isNegativeInteger( 0.0 );
// returns false
bool = isNegativeInteger( 10.0 );
// returns false
The function assumes a finite number
. If provided negative infinity
, the function will return true
, when, in fact, the result is undefined. If x
can be infinite
, wrap the implementation as follows:
function check( x ) {
return (
x > -Infinity &&
isNegativeInteger( x )
);
}
var bool = check( -Infinity );
// returns false
var isNegativeInteger = require( '@stdlib/math-base-assert-is-negative-integer' );
var bool = isNegativeInteger( -5.0 );
// returns true
bool = isNegativeInteger( 0.0 );
// returns false
bool = isNegativeInteger( 1.0 );
// returns false
bool = isNegativeInteger( -3.14 );
// returns false
bool = isNegativeInteger( NaN );
// returns false
