Hello Team,
I am a security researcher and I founded this vulnerability in your website.
I just sent a forged email to my email address that appears to originate from pgsql-www@postgresql.org. I was able to
dothis because of the following DMARC record:
DMARC record lookup and validation for: postgresql.org
" DMARC Quarantine/Reject policy not enabled "
How To Reproduce(POC-ATTACHED IMAGE):-
1.Go To- mxtoolbox.com/DMARC.aspx
2.Enter the Website.CLICK GO.
3.You Will See the fault(DMARC Quarantine/Reject policy not enabled)
Fix:
1)Publish DMARC Record.
2)Enable DMARC Quarantine/Reject policy
For more information you can use this blog
(https://sendgrid.com/blog/what-is-dmarc/).
<?php
$to = "VICTIM@example.com";
$subject = "Password Change";
$txt = "Change your password by visiting here - [VIRUS LINK HERE]l";
$headers = "From:pgsql-www@postgresql.org";
mail($to,$subject,$txt,$headers);
?>

Let me know if you need me to send another forged email, or if have any other questions.
Hoping for the bounty for my ethical Disclosure.
Kind Regards
Security Researcher
