9.6 CRITICALEPSS 0.52%
  1. Published3 Jan 2024

Description

A host header injection vulnerability exists in the NPM package @perfood/couch-auth versions <= 0.20.0. By sending a specially crafted host header in the forgot password request, it is possible to send password reset links to users which, once clicked, lead to an attacker-controlled server and thus leak the password reset token. This may allow an attacker to reset other users' passwords and take over their accounts.
