                     CVE-2026-33174 CVE-2026-33176 CVE-2026-33195 CVE-2026-33202
                     CVE-2026-33658 CVE-2026-66066

    Multiple security issues were discovered in the Rails web framework
    which could result in cross-site scripting, denial of service, path
    traversal or the execution of arbitrary code.

    For the stable distribution (trixie), these problems have been fixed in
    version 2:7.2.2.2+dfsg-2~deb13u2.

    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 Security Advisories, how to apply
    these updates to your system and frequently asked questions can be
