Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Reflection utilities are highly sensitive; flaws in stack-frame analysis (like treating the utility itself or cache infrastructure as a trusted caller) allow callers to bypass reflection security blocks and invoke restricted methods.
Auth Bypass: Attackers can bypass class blocklists by nesting forbidden classes within array descriptors or using custom class loaders, requiring explicit component-type validation.
Path Traversal: File transfer mechanisms that accept user-provided paths without canonicalization can write to or read from arbitrary locations on the file system.
