user password containing "

[ustk]

@dannytaurus strange it's not forbidden by default...

[David Healey]

@ustk Yes I ran into this issue too a few years ago. I think it's the JWT plugin that was the issue, can't remember now.

I added this snippet to my site to prevent users using quotations marks in their passwords.

function prevent_quotation_mark_passwords($errors, $user) {
    if (strpos($user->user_pass, '"') !== false || strpos($user->user_pass, "'") !== false) {
        $errors->add('password_error', __('The password cannot contain quotation marks.', 'your-text-domain'));
    }

    return $errors;
}

add_filter('registration_errors', 'prevent_quotation_mark_passwords', 10, 2);
add_filter('user_profile_update_errors', 'prevent_quotation_mark_passwords', 10, 2);
add_filter('woocommerce_registration_errors', 'prevent_quotation_mark_passwords', 11, 3);
add_filter('woocommerce_save_account_details_errors', 'prevent_quotation_mark_passwords', 10, 3);

function custom_password_reset_validation($errors, $user) {
    $new_password = isset($_POST['password_1']) ? wc_clean($_POST['password_1']) : '';

    // Check if the password contains quotation marks
    if (strpos($new_password, '"') !== false || strpos($new_password, "'") !== false) {
        $errors->add('password_reset_error', __('The password cannot contain quotation marks.', 'your-text-domain'));
    }

    return $errors;
}

add_action('validate_password_reset', 'custom_password_reset_validation', 10, 2);

@ustk
Oh, good to know!

[ustk]

@David-Healey Oh nice

What about the backslash escape char \? I'm afraid it can too lead to issues...

I am testing a plugin called WP Password Policy. For now the special chars can't be specified but I just reached out the team and they said it's a nice addition so they'll push it along with the next update in about a week... Very reactive

Haven't ran in to any issues there

[ustk]

@David-Healey I just confirmed that \ also leads to issues, so you better add this rule to your current snippet

@ustk I ended up fixing the issue in the JWT wordpress plugin.
I was having issues with special characters as well

@Dan-Korneff Did you make a PR?

The 10 grand question

[Dan Korneff]

@David-Healey they didn't seem interested, so I'm maintaining my own fork. Maybe you can strip the update from my repo and make a PR?

[David Healey]

@Dan-Korneff or I'll just use your fork got a link?
