Django Potential Denial of Service (DoS) on Windows
An issue was discovered in Django 5.1 before 5.1.8 and 5.0 before 5.0.14. The NFKC normalization is slow on Windows. As a consequence, django.contrib.auth.views.LoginView, django.contrib.auth.views.LogoutView, and django.views.i18n.set_language are subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.
Django vulnerable to Allocation of Resources Without Limits or Throttling
An issue was discovered in Django 5.1 before 5.1.7, 5.0 before 5.0.13, and 4.2 before 4.2.20. The django.utils.text.wrap() method and wordwrap template filter are subject to a potential denial-of-service attack when used with very long strings.
Django has a potential denial-of-service vulnerability in IPv6 validation
An issue was discovered in Django 5.1 before 5.1.5, 5.0 before 5.0.11, and 4.2 before 4.2.18. Lack of upper-bound limit enforcement in strings passed when performing IPv6 validation could lead to a potential denial-of-service attack. The undocumented and private functions clean_ipv6_address and is_valid_ipv6_address are vulnerable, as is the django.forms.GenericIPAddressField form field. (The django.db.models.GenericIPAddressField model field is not affected.)
Django SQL injection in HasKey(lhs, rhs) on Oracle
An issue was discovered in Django 5.1 before 5.1.4, 5.0 before 5.0.10, and 4.2 before 4.2.17. Direct usage of the django.db.models.fields.json.HasKey lookup, when an Oracle database is used, is subject to SQL injection if untrusted data is used as an lhs value. (Applications that use the jsonfield.has_key lookup via __ are unaffected.)
Django ReDoS in strip_tags()
Denial of service via catastrophic backtracking in django.utils.html.strip_tags() with crafted input.
Django allows enumeration of user e-mail addresses
An issue was discovered in Django v5.1.1, v5.0.9, and v4.2.16. The django.contrib.auth.forms.PasswordResetForm class, when used in a view implementing password reset flows, allows remote attackers to enumerate user e-mail addresses by sending password reset requests and observing the outcome (only when e-mail sending is consistently failing).
Django urlize() XSS
django.utils.html.urlize() did not escape certain HTML characters, leading to XSS.
Django SQL injection vulnerability
An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. QuerySet.values() and values_list() methods on models with a JSONField are subject to SQL injection in column aliases via a crafted JSON object key as a passed *arg.
Django vulnerable to denial-of-service attack
An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. The urlize and urlizetrunc template filters, and the AdminURLFieldWidget widget, are subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.
Django vulnerable to a denial-of-service attack
An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. The urlize() and urlizetrunc() template filters are subject to a potential denial-of-service attack via very large inputs with a specific sequence of characters.
Django memory consumption vulnerability
An issue was discovered in Django 5.0 before 5.0.8 and 4.2 before 4.2.15. The floatformat template filter is subject to significant memory consumption when given a string representation of a number in scientific notation with a large exponent.
Django vulnerable to Denial of Service
An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. get_supported_language_variant() was subject to a potential denial-of-service attack when used with very long strings containing specific characters.
Django Path Traversal vulnerability
An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. Derived classes of the django.core.files.storage.Storage base class, when they override generate_filename() without replicating the file-path validations from the parent class, potentially allow directory traversal via certain inputs during a save() call. (Built-in Storage sub-classes are unaffected.)
Django vulnerable to user enumeration attack
An issue was discovered in Django 5.0 before 5.0.7 and 4.2 before 4.2.14. The django.contrib.auth.backends.ModelBackend.authenticate() method allows remote attackers to enumerate users via a timing attack involving login requests for users with an unusable password.
Django URLValidator ReDoS
URLValidator susceptible to ReDoS with specially crafted URLs.
Pillow buffer overflow vulnerability
In _imagingcms.c in Pillow before 10.3.0, a buffer overflow exists because strcpy is used instead of strncpy.
Regular expression denial-of-service in Django
In Django 3.2 before 3.2.25, 4.2 before 4.2.11, and 5.0 before 5.0.3, the django.utils.text.Truncator.words() method (with html=True) and the truncatewords_html template filter are subject to a potential regular expression denial-of-service attack via a crafted string. NOTE: this issue exists because of an incomplete fix for CVE-2019-14232 and CVE-2023-43665.
Django denial-of-service attack in the intcomma template filter
An issue was discovered in Django 3.2 before 3.2.24, 4.2 before 4.2.10, and Django 5.0 before 5.0.2. The intcomma template filter was subject to a potential denial-of-service attack when used with very long strings.
Arbitrary Code Execution in Pillow
Pillow through 10.1.0 allows PIL.ImageMath.eval Arbitrary Code Execution via the environment parameter, a different vulnerability than CVE-2022-22817 (which was about the expression parameter).
Pillow Denial of Service vulnerability
An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.
