Do gun safes rust guns?

Could you please clarify whether gun safes have the potential to cause rusting on firearms stored within? I've heard rumors about humidity accumulation and condensation within safes, leading to corrosion on weapons. Is this a common occurrence, or are there certain types of safes or maintenance practices that can prevent such issues? As a gun owner, it's crucial for me to ensure my firearms are properly stored and protected from damage, so any insight you can provide would be greatly appreciated.
