Summary:

The code changes in this pull request are focused on improving the security of the password change functionality and the overall code quality through the use of a linter configuration.

The changes to the unittests/test_user_validators.py file introduce various password policy validations, such as checking for minimum and maximum length, the presence of numbers, special characters, uppercase and lowercase letters, and non-common passwords. These validations help ensure that users choose strong and secure passwords, reducing the risk of password-related attacks. Additionally, the code checks that the user's current password is correct before allowing a password change and prevents password reuse, further enhancing the security of the password change process.

The changes to the ruff.toml file, which is the configuration file for the Ruff linter, indicate a focus on improving the security of the codebase. The addition of the S106 rule, which is part of the "Flake8 Security" set of rules, suggests that the developers are adding a new security-related check. However, the removal of some other security-related rules should be carefully reviewed to ensure that it does not introduce any security vulnerabilities.

Files Changed:

1. unittests/test_user_validators.py: This file contains test cases for the ChangePasswordForm form, which is responsible for validating password changes. The changes introduce various password policy validations, such as minimum and maximum length, the presence of numbers, special characters, uppercase and lowercase letters, and non-common passwords. Additionally, the code checks that the user's current password is correct before allowing a password change and prevents password reuse.

2. ruff.toml: This file is the configuration file for the Ruff linter, which is a Python code linter. The changes include the addition of the S106 rule, which is part of the "Flake8 Security" set of rules, and the removal of several other security-related rules. The addition of the S106 rule is a positive change, as it indicates a focus on improving the security of the codebase. However, the removal of the other security-related rules should be carefully reviewed to ensure that it does not introduce any security vulnerabilities.
