Possible image tampering from missing image validation for Packages

Impact

Crossplanes 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.

Patches

The problem has been fixed in 1.11.5, 1.12.3 and 1.13.0, all the supported versions of Crossplane at the time of writing.

Workarounds

Only using images from trusted sources and keeping Package editing/creating privileges to administrators only, which should be both considered already best practices.
