Put simply

Think of it like an employee who somehow finds a way to access the executive lounge without the right badge — they can see confidential plans and even change the company’s direction! This incorrect privilege assignment in Modular DS's modular-connector allows unauthorized users to elevate their privileges. Specifically, versions 2.5.2 to just before 2.6.0 are affected, putting many installations at risk.
