django-allauth before 65.19.4 does not have the expected limits on failed login attempts because, in some common configurations, an attacker can leverage the handling of diacritics (e.g., accents) for a higher effective limit.
An open redirect vulnerability exists in django-allauth versions prior to 65.14.1 when SAML IdP initiated SSO is enabled (it is disabled by default), which may allow an attacker to redirect users to an arbitrary external website via a crafted URL.
