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: [email protected]” in its release
description, is not vulnerable).
