The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5389 advisory.

    Two vulnerabilities were discovered in rails, the Ruby based server-side MVC web application framework,     which could lead to XSS and DOM based cross-site scripting (CRS). This update also fixes a regression     introduced in previous update that may block certain access for applications using development     environment. For the stable distribution (bullseye), these problems have been fixed in version     2:6.0.3.7+dfsg-2+deb11u2. We recommend that you upgrade your rails packages. For the detailed security     status of rails please refer to its security tracker page at: https://security-     tracker.debian.org/tracker/rails
