summary 
ERB has an @_init deserialization guard bypass via def_module / def_method / def_class
ERB implements an @_init guard to prevent code execution when ERB
objects are reconstructed via Marshal.load on untrusted data. However,
ERB#def_method, ERB#def_module, and ERB#def_class evaluate the template
source without checking this guard, allowing an attacker who controls
the data passed to Marshal.load to bypass the protection and execute
arbitrary code. In particular, def_module takes no arguments, making
it straightforward to invoke as part of a deserialization gadget chain.

Please update to Ruby 4.0.3 which "only contains ERB 6.0.1.1,
which fixes CVE-2026-41316."
