    Debian Bugs    : 1107282 1104872 1051226

    A number of vulnerabilities were discovered in Django, a popular
    Python-based web-development framework:

     * CVE-2025-48432: Potential log injection via unescaped request path.

       Django's internal HTTP response logging used request.path directly,
       allowing control characters (e.g. newlines or ANSI escape sequences) to
       be written unescaped into logs. This could enable log injection or
       forgery, letting attackers manipulate log appearance or structure,
       especially in logs processed by external systems or viewed in terminals.
       (Closes: #1107282)

     * CVE-2025-32873: Denial-of-service possibility in strip_tags()

       django.utils.html.strip_tags() would be slow to evaluate certain inputs
       containing large sequences of incomplete HTML tags. This function is used
       to implement the striptags template filter, which was therefore also
       vulnerable. strip_tags() now raises a SuspiciousOperation exception if it
       encounters an unusually large number of unclosed opening tags.
       (Closes: #1104872)

     * CVE-2023-41164: Potential denial of service vulnerability in
       django.utils.encoding.uri_to_iri(). This method was subject to potential
       denial of service attack via certain inputs with a very large number of
       Unicode characters. (Closes: #1051226)

     * CVE-2023-43665: Address a denial-of-service possibility in
       django.utils.text.Truncator.

       Following the fix for CVE-2019-14232, the regular expressions used in the
       implementation of django.utils.text.Truncator??s chars() and words()
       methods (with html=True) were revised and improved. However, these
       regular expressions still exhibited linear backtracking complexity, so
       when given a very long, potentially malformed HTML input, the evaluation
       would still be slow, leading to a potential denial of service
       vulnerability. The chars() and words() methods are used to
       implement the truncatechars_html and truncatewords_html template
       filters, which were thus also vulnerable. The input processed by
       Truncator, when operating in HTML mode, has been limited to the
       first five million characters in order to avoid potential
       performance and memory issues.

     * CVE-2024-24680: Potential denial-of-service in intcomma template
       filter. The intcomma template filter was subject to a potential
       denial-of-service attack when used with very long strings.

     * CVE-2024-27351: Fix a potential regular expression denial-of-service
       (ReDoS) attack in django.utils.text.Truncator.words. This method (with
       html=True) and the truncatewords_html template filter were subject to a
       potential regular expression denial-of-service attack via a suitably
       crafted string. This is, in part, a follow up to CVE-2019-14232 and
       CVE-2023-43665.

    For Debian 11 bullseye, these problems have been fixed in version
    2:2.2.28-1~deb11u7.

    We recommend that you upgrade your python-django packages.
