    Package        : golang-github-gorilla-csrf
    Version        : 1.6.2-2+deb11u1
    CVE ID         : CVE-2025-24358
    Debian Bug     : 1103584

    The following vulnerability has been discovered in the gorilla/csrf package for Go:

        Prior to 1.7.3, gorilla/csrf did not validate the Origin header against
        an allowlist. It executed its validation of the Referer header for
        cross-origin requests only when it believed the request was being
        served over TLS. It determined this by inspecting the r.URL.Scheme
        value. However, this value was never populated for server requests
        per the Go spec, and so this check did not run in practice. This
        vulnerability allowed an attacker who has gained XSS on a subdomain
        or top level domain to perform authenticated form submissions against
        gorilla/csrf protected targets that shared the same top level domain.

    For Debian 11 bullseye, this problem has been fixed in version
    1.6.2-2+deb11u1.

    The following Go packages have been rebuilt in order to fix this
    issue:

    golang-chroma
    golang-github-alecthomas-chroma-dev
    golang-github-niklasfasching-go-org-dev
    golang-github-yuin-goldmark-highlighting-dev
    go-org
    hugo

    We recommend that you upgrade these packages.
