What is incomprehensible here?

I agree that the message should be better worded. For example:

"Admin name is too long (maximum 50 characters are allowed)"

@DenisChenu can you clarify how you would change this error notification?

Adding the error return by save()

"Admin name is too long (maximum 50 characters are allowed)" for admin
"Admin email must be a valid email"

etc …

Using https://www.yiiframework.com/doc/api/1.1/CHtml#errorSummary-detail ?

errorSummary use

1. rules : https://github.com/LimeSurvey/LimeSurvey/blob/6a578fb773c2397aa58e3034f8c0fb6e2bcc5e44/application/models/Survey.php#L480
2. labels https://github.com/LimeSurvey/LimeSurvey/blob/5.X/application/models/Survey.php#L220 (or name of attribute)

What is incomprehensible here?

What error we have : in 6.X : we check email too : you can have error on admin name AND./OR admin email.

Ergonomy :

1. Be clear on error when an error happen (explain)
2. Shown a lot of error with a link to the error (i don't ask it …)
3. If possible don't validate a form i there are error (Yii can do it with activeField (or we can add it manually here))

I juts ask 1 : no less ergonomie than 5.X : be better, but not worse

I read it wrong from your description "In 5.X : we have the issue, not in 6".

So I thought the issue/bug is in 5.x. All good, I understand now.

Oh roght !

I mean
In 5.X : we have the error shown, not in 6

It's not just an error message guy's it's proper Stored XSS, if you think it is not make the original reported issue as public.
Instead of fixing the issue you're just playing around, Let me know if i can share poc's to prevent the user's from this bug.

Kindly mark this issue as public please.
