Official description

Crossplane is a framework for building cloud native control planes without needing to write code. In versions prior to 1.11.5, 1.12.3, and 1.13.0, Crossplane's image backend does not validate the byte contents of Crossplane packages. As such, Crossplane does not detect if an attacker has tampered with a Package. The problem has been fixed in 1.11.5, 1.12.3 and 1.13.0. As a workaround, only use images from trusted sources and keep Package editing/creating privileges to administrators only.
