What it is

⚠️ WordPress versions before 5.5.2 have a sneaky way of mishandling deserialization requests, like a restaurant serving a dish without checking the recipe! Picture a chef who blindly prepares meals without confirming the allergen list provided by customers—serving up potential chaos! Just like that, this vulnerability can lead to unexpected outcomes in your WordPress site. An attacker could exploit this mishandling to manipulate the behavior of the application, leading to data exposure or even corruption. This could mean unauthorized access to sensitive information, which is absolutely devastating for any website owner.

Put simply
