Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The PyPI package cobbler, versions from 2.6.0 up to but not including 3.0.0, exposed all functions of its CobblerXMLRPCInterface class over XMLRPC. A remote attacker with no authentication could use this to gain elevated privileges in cobbler and upload files to arbitrary locations in the context of the daemon. Upgrade to cobbler 3.0.0, which contains the fix.
