    Package        : rails
    Version        : 2:6.0.3.7+dfsg-2+deb11u4
    CVE ID         : CVE-2025-24293 CVE-2025-55193
    Debian Bug     : 1111106

    Multiple security issues were discovered in the Rails web framework
    which could result in command injection or logging of unescaped ANSI
    sequences.

    For Debian 11 bullseye, these problems have been fixed in version
    2:6.0.3.7+dfsg-2+deb11u4.

    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

    Further information about Debian LTS security advisories, how to apply
    these updates to your system and frequently asked questions can be
