Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Concrete CMS (concrete5/concrete5) versions below 8.5.10 and from 9.0.0 up to 9.1.2 are vulnerable to XML External Entity (XXE) processing that can trigger DNS requests, leaking the server's IP address. The source does not describe what level of access an attacker needs to exploit this. Upgrade to version 8.5.10 or 9.1.2, depending on the release line in use.
