You left out CVE-2025-23121 - which has a “Critical” priority - but that’s because we’ve all followed Best Practices and our VBRs aren’t domain joined, right? :D

 

And yes, I haven’t even finished applying 12.3.1 yet.

Thinking on CVE 2025-1094, why Veeam not include a newer version of postgre on ISO?

Thank you for the update ​@coolsport00 

Yes, I also received the email sent by Veeam as well for this important update.

It’s good to see the quick response from the community and the vendor to limit the attacker impact on this vulnerabilities.
