Question New Posts email notification in a read-only forum!

Hello,

I'm running Kunena 5.1.1 with J 3.8.8 and these past couple of days I have been receiving email notifications about new (spam) posts in existing topics however when i visit the topics I am not seeing any new posts there!

Here is a sample of the email notification:

In order to stop this activity I set the form to "Read Only" mode but this is continuing.

Any ideas? Is this perhaps a bug or is there something suspicious going on which I should be concerned about?

Many thanks for your time and help.

Chris.

I am having the exact same issue and am very concerned. I am also on 5.1.1. Users are reporting this via email, yet no such post exists. Here is one of the emails sent to me:

Do not answer to this e-mail notification as it is a generated e-mail.

While no one has replied with a solution I have found a work-around.
I dug into the apache logs and found which IP address was hitting the URL with HTTP POST command - the IP was identical in all events so I simply blocked the abusive IP address in the site's .htaccess file.

No longer receiving the alerts however I'm suspecting this is a bug.

Thanks,

Me too

Situation is almost the same. I have installed the newest kunena and joomla version and receive sometimes auto notifications for threads with sender "???" who is replying to a topic. In fact these are spam mails and when checking the forum there is no new entry and also there were no user log in Joomla / Kunena at this time (but could be that a user logged in days ago...)
So no idea from where this is coming from but high level it looks like a security bug.

Would be great to get a developer response. Banning IP's works, but I am assuming they are going to start coming from all directions soon.

Could you please all add the kunena report. And how your category is setup with the permissions.

Also please enable kunena logs. setting Is on the configuration. That feature will log all users actions. So maybe I know then how they to it.
