Package : node-hawk
Version : 6.0.1+dfsg-1+deb10u1
CVE IDs : CVE-2022-29167

It was discovered that there was an issue in Hawk, an HTTP
authentication scheme. Hawk used a regular expression to parse `Host`
HTTP headers which was subject to regular expression DoS attack. Each
added character in the attacker's input increased the computation
time exponentially.

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

We recommend that you upgrade your node-hawk packages.
