    CVE ID         : CVE-2026-48587 CVE-2026-48588
    Debian Bug     : 1138775 1141629

    Multiple vulnerabilities were discovered in Django, the Python-based
    web development framework:

    CVE-2026-48587

        Potential exposure of private data via whitespace padding in Vary
        header. django.middleware.cache.UpdateCacheMiddleware incorrectly
        cached responses whose Vary header values contained leading or
        trailing whitespace. Because has_vary_header failed to strip that
        whitespace, a response with a Vary: *  header (note the
        trailing space) was not recognized as containing the wildcard,
        causing it to be stored and potentially served from the cache
        when it should not have been.

    CVE-2026-48588

        UpdateCacheMiddleware and the @cache_page decorator cached
        responses that vary on cookies when the incoming request carried
        unrelated cookies, which allowed remote attackers to read private
        data from the shared cache.

    For Debian 12 bookworm, these problems have been fixed in version
    3:3.2.25-0+deb12u5.

    We recommend that you upgrade your python-django packages.
