qs: qs: Denial of Service via improper validation in stringify function

A flaw was found in qs. The qs.stringify function, responsible for serializing objects, does not properly validate the isBuffer property of an object's constructor before attempting to invoke it. An unauthenticated attacker can provide specially crafted input that, when processed and then...

qs: qs: Denial of Service due to improper handling of null/undefined array elements

A flaw was found in the qs library. When the qs.stringify function processes arrays containing null or undefined elements, and is configured with both arrayFormat: 'comma' and encodeValuesOnly: true, it can trigger a TypeError. This error causes the application to crash or return a 500 error,...
