Security issues
CVE-2021-32763: Regular Expression Denial of Service in OpenProject forum messages
An unoptimized regular expression in the quote functionality of the OpenProject forum feature in versions before 11.3.3 allows an attacker to perform a denial of service attack by passing a particularly crafted string to increase the runtime of the regular expression evaluation drastically.
Please see the advisory for CVE-2021-32763 for more information.
CVE-2021-36390: Host Header Injection in unproxied Docker installations
The default ServerName configuration of the all-in-one and docker-compose based Docker containers of OpenProject allow for HOST header injection if they are operated without a proxying web server / load balancer in front of it with a proper ServerName setup.
Operating public facing docker containers is not recommended by OpenProject. The embedded server of the docker containers are not designed to be publicly accessible. Instead, use a proxying or load balancing web server that is bound to your public hostname. If you are using such an external web server, this advisory does not affect you.
Please see the advisory for CVE-2021-36390 for more information.
