Dear Maintainer,
davical installs the file /etc/apache2/sites-available/davical.conf. The Content-Security-Policy is defined in apache global scope,
so other programs like roundcube do not work with this CSP!
<FilesMatch "(admin|help|iSchedule|index|metrics|public|setup|tools|upgrade).php">
Header set Content-Security-Policy ...
</FilesMatch>
Fix: The CSP should be defined for davical only - not globally, e.g.
<Directory /usr/share/davical/htdocs>
<FilesMatch "(admin|help|iSchedule|index|metrics|public|setup|tools|upgrade).php">
Header set Content-Security-Policy ...
</FilesMatch>
</Directory>
Hi Andreas, this was fixed in DAViCal 1.1.13, now in Debian testing. You can just download the davical 1.1.13 and libawl-php 0.65 packages from testing and install them on trixie, or I could upload a backport of both, if you'd rather install from trixie-backports? Best, Florian
