    Multiple vulnerabilities were discovered in Node.js, which could result
    in denial of service, permission model bypass, incorrect certificate
    validation or information disclosure.

    For the stable distribution (trixie), these problems have been fixed in
    version 20.19.2+dfsg-1+deb13u3.

    We recommend that you upgrade your nodejs packages.

    For the detailed security status of nodejs please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/nodejs
