There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Action View provides conventions and helpers for building web pages with the Rails framework. Prior to
    versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when a blank string is used as an HTML attribute name in Action
    View tag helpers, the attribute escaping is bypassed, producing malformed HTML. A carefully crafted
    attribute value could then be misinterpreted by the browser as a separate attribute name, possibly leading
    to XSS. Applications that allow users to specify custom HTML attributes are affected. Versions 8.1.2.1,
    8.0.4.1, and 7.2.3.1 contain a patch. (CVE-2026-33168)

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6546 advisory.

    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.

    Package        : rails     Version        : 2:6.1.7.10+dfsg-1~deb12u3     CVE ID         : CVE-2026-33168 CVE-2026-33169 CVE-2026-33170 CVE-2026-33173                      CVE-2026-33176 CVE-2026-33195 CVE-2026-33202 CVE-2026-66066     Debian Bug     : 1132035 1143080

    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.

    CVE-2026-33168

        In Action View, tag helpers skipped escaping when an HTML attribute         name was blank, which could allow cross-site scripting. Blank         attribute names are now dropped.

    CVE-2026-33169

        In Active Support, number_to_delimited took quadratic time on long         digit strings, which could be used for a denial of service.

    CVE-2026-33170

        In Active Support, formatting an unsafe SafeBuffer with % marked         the result as html_safe, which could allow cross-site scripting.
        The result now stays unsafe.

    CVE-2026-33173

        In Active Storage, a direct upload could set the analyzed and         identified metadata keys and skip content-type detection. Those         keys are now dropped from client-supplied metadata.

    CVE-2026-33176

        In Action View, number helpers expanded scientific notation through         BigDecimal, so input such as 1E1000 could use excessive CPU and         memory, leading to a denial of service.

    CVE-2026-33195

        In Active Storage, the disk service accepted keys containing ../,         which allowed path traversal outside the storage root. Such keys now         raise InvalidKeyError.

    CVE-2026-33202

        In Active Storage, the disk service's delete_prefixed passed the         prefix to Dir.glob without escaping, so glob metacharacters could         delete unintended files. Glob metacharacters are now escaped.

    CVE-2026-66066

        In Active Storage, applications that set the variant processor to         :vips left libvips's untrusted, unfuzzed loaders enabled, which could         allow crafted images to execute arbitrary code. The vips processor         now blocks untrusted loaders. The default MiniMagick processor is         not affected.

    For Debian 12 bookworm, these problems have been fixed in version     2:6.1.7.10+dfsg-1~deb12u3.

    We recommend that you upgrade your rails packages.
