    Package        : python-django
    Version        : 2:2.2.28-1~deb11u12
    CVE IDs        : CVE-2025-13473 CVE-2026-1207 CVE-2026-1285 CVE-2026-1287 CVE-2026-1312 CVE-2025-6069
    CVE-2025-57833

    It was discovered that there were multiple vulnerabilities in Django,
    the Python-based web-development framework:

    - - CVE-2025-13473: The check_password function in
      django.contrib.auth.handlers.modwsgi for authentication via
      mod_wsgi allowed remote attackers to enumerate users via a timing
      attack.

    - - CVE-2026-1207: Raster lookups on RasterField (only implemented on
      PostGIS) allowed remote attackers to inject SQL via the band index
      parameter.

    - - CVE-2026-1285: The django.utils.text.Truncator.chars() and
      Truncator.words() methods (with html=True) and the
      truncatechars_html and truncatewords_html template filters allowed
      a remote attacker to cause a potential denial-of-service via
      crafted inputs containing a large number of unmatched HTML end
      tags.

    - - CVE-2026-1287: FilteredRelation was subject to SQL injection in
      column aliases via control characters using a suitably crafted
      dictionary, with dictionary expansion, as the **kwargs passed to
      QuerySet methods annotate(), aggregate(), extra(), values(),
      values_list() and alias().

    - - CVE-2026-1312: QuerySet.order_by() was subject to SQL injection
      in column aliases containing periods when the same alias is, using
      a suitably crafted dictionary, with dictionary expansion, used in
      FilteredRelation.

    In addition, the fix for CVE-2025-6069 in the python3.9 source
    package (released as part of a suite of updates in DLA 4445-1)
    modified Python's html.parser.HTMLParser class in such a way that
    changed the behaviour of Django's strip_tags() method in some edge
    cases that were tested by Django's testsuite. As a result of this
    regression, we have updated the testsuite for the new expected
    results.

    For Debian 11 bullseye, this problem has been fixed in version
    2:2.2.28-1~deb11u12.

    We recommend that you upgrade your python-django packages.
