Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Remote Code Execution: Attackers can supply malicious property paths to access and manipulate properties of the Java ClassLoader (such as 'class.classLoader') through the bean introspection engine. This enables arbitrary code execution in environments that do not default to suppressing class-level property resolution.

Remote Code Execution: On enum-typed properties, attackers can traverse through the 'declaringClass' property to regain access to ClassLoader manipulation vectors, bypassing existing 'class' suppression rules. Default suppression of declaringClass on enums is required.

Sandbox Escape: Without explicit property suppression mechanisms embedded in the IntrospectionContext, standard bean property population flows can be abused to retrieve nested system objects, leading to sandbox escapes.
