Summary
The Create Block WordPress plugin before 2.10.0 does not correctly escape user-supplied text before writing it into a generated PHP pattern file, allowing a multisite subsite administrator (who holds the capability gating this action but is denied the capability that normally gates PHP file editing) to inject and execute arbitrary PHP code on the server.
