Pragma non-specification can lead to non-functional / corrupted contract when deployed on Arbitrum
Summary
Pragma has been set to ^0.8.19 allowing the contracts to be compiled with a compiler equal or greater than 0.8.19. The problem with compiling is that Arbitrum is NOT compatible with 0.8.20 and later.
Vulnerability Details
Contracts compiled with non specified versions will result in a non-functional or potentially damaged version that won't behave as expected. The default behaviour of compiler would be to use the newest version which would mean by default it will be compiled with the 0.8.20 version which will produce broken code.
Impact
Corrupted or non-functional contracts when deployed on Arbitrum.
