UPDATE:
I checked:
https://ubuntu.com/security/CVE-2026-109618
https://ubuntu.com/security/CVE-2026-109619
and php8.1 in 22.04 LTS jammy has status "Fixed in 8.1.2-1ubuntu2.28" (backporting?).

After, I checked my installation with:
dpkg -l | grep php8.1-cli
and it reports:
ii php8.1-cli 8.1.2-1ubuntu2.28 amd64 command-line interpreter for the PHP scripting language

so I think I'm ok for now.

Hope this is useful to anyone in the same guessing situation.

If I'm wrong, please let me know.

Hello. Following Critical PHP vulnerabilities announcement , I checked php version on my iRedMail EE installation on Ubuntu 22.04.5 LTS and found RoundCube uses php 8.1 (the default version for v22.04).

Is anyone in the same situation. Any suggestion how address this?

I was thinking to add the 8.3 repository, installing it and changing iRedMail configuration so that 8.3 is used instead of 8.1; but I have no idea if this could interfere with RedMail EE auto deployment.

Long term plan could be creating a new server with Ubuntu 26.04 and migrate mailboxes, but in the meantime? In-place upgrade is out of question.

As of now I closed access to Roundcube from external, to prevent exploiting php vulnerability.

Ideas welcomed.
