CVE-2023-38495 Information

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.
