Internal State Exposure in ThemeList.java Class:

[BearSolitary]

I’ve identified a security vulnerability related to the exposure of the internal representation in the “ThemeList.java” class.

Method getThemes() in the ThemeList.java class returns a direct reference to its private ‘themes’ list. Therefore, any caller can maliciously modify internal representation leading to data corruption. For example, the caller can perform the operation “themeList.getTHemes().clear()” and clear the data in the list.
