OESA-2024-1338

This is a query string parser for node and the browser supporting nesting, as it was removed from 0.3.x, so this library provides the previous and commonly desired behavior (and twice as fast). Used by express, connect and others.

Security Fix(es):

qs before 6.10.3, as used in Express before 4.17.3 and other products, allows attackers to cause a Node process hang for an Express application because an _ proto_ key can be used. In many typical Express use cases, an unauthenticated remote attacker can place the attack payload in the query string of the URL that is used to visit the application, such as a[proto]=b&a[proto]&a[length]=100000000. The fix was backported to qs 6.9.7, 6.8.3, 6.7.3, 6.6.1, 6.5.3, 6.4.1, 6.3.3, and 6.2.4 (and therefore Express 4.17.3, which has "deps: qs@6.9.7" in its release description, is not vulnerable).(CVE-2022-24999)
