We’ve released Zammad 6.5.3, which includes all backportable fixes for users who are still on version 6.5 and cannot upgrade to version 7.0 yet.
No action is required for SaaS environments, as they are already running version 7.0.
Full details are available in the release notes and related security advisories: Security release: Zammad 6.5.3
Hello, please will be the Zammad 6.5.3 available also as deb package ? Currently I see still just 6.5.2 in the repo for Debian (13).
Thanks in advance 
Debian 13 is supported starting with Zammad 7.0 and thus not part of this backport.
Thx for info. Interesting, for me the 6.5.2 is running fine on Debian 13 but yeah probably still the package from Deb 12 repo…
There‘s no packes for debian 13 for Zammad 6.x, so yeah, just ‚wrong‘ dist upgrade.
@MrGeneration @JuliaDenise But supported Ubuntu 24.04 also misses 6.5.3 package?
Should be present: Installation of zammad/zammad v6.5.3 for Ubuntu Noble 24.04 64 bits
Okay, means Ubuntu users need this APT repo change to get the security update:
sed -i "s/zammad\/stable\/ubuntu/zammad\/stable-6.5\/ubuntu/g" /etc/apt/sources.list.d/zammad.list
@dominikklein Maybe you can push 6.5.3 into stable to supersede 6.5.2?
This would follow Ubuntu upstream practice to ensure only patched installables.
stable is pointing to 7.0.0. You should use stable-6.5 I guess (if still using Zammad 6.5.x).
Hello,
How can we upgrade with docker zammad 6.5.2 to 6.5.3 ??
