Package        : node-qs
Version        : 6.5.2-1+deb10u1
CVE ID         : CVE-2022-24999

Nathanael Braun and Johan Brissaud discovered a prototype poisoning
vulnerability in node-qs, a Node.js module to parse and stringify query
strings.  node-qs 6.5.x before 6.5.3 allows for instance the creation of
array-like objects by setting an Array in the `__ proto__` property; the
resulting Objects inherit the `Array` prototype, thereby exposing native
Array functions.

For Debian 10 buster, this problem has been fixed in version
6.5.2-1+deb10u1.

We recommend that you upgrade your node-qs packages.

For the detailed security status of node-qs please refer to
