Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Remote Code Execution: The traversal of Python dunder attributes inside Delta objects could allow attackers to access restricted object constructors or methods, leading directly to arbitrary code execution.
Prototype Pollution: Attackers can bypass path validations (like check_elem) to inject malicious dunder-attribute paths, risking class/prototype pollution and state compromise.
Denial of Service: Unbounded constructor arguments in _RestrictedUnpickler permit memory exhaustion attacks when loading crafted pickle payloads, crashing the application.
