Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-303: Incorrect Implementation of Authentication Algorithm, where the requirements for the product dictate the use of an established authentication algorithm, but the implementation of the algorithm is incorrect. In Social auth app django, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Upon authentication, the user could be associated by e-mail even if the `associate_by_email` pipeline was not included. This could lead to account compromise when a third-party authentication service does not validate provided e-mail addresses or doesn't require unique e-mail addresses. ### Patches * https://github.com/python-social-auth/social-app-django/pull/803 ### Workarounds Review the authentication service policy on e-mail addresses; many will not allow exploiting this vulnerability.
