On the Robustness of Tabular Foundation Models: Test-Time Attacks and In-Context Defenses

Researchers have uncovered significant vulnerabilities in recent tabular foundational models like TabPFN and TabICL, showing that small input perturbations can severely impact prediction accuracy across finance, cybersecurity, and healthcare benchmarks. This highlights the need for developers to implement robust training methods such as adversarial fine-tuning or context optimization to protect against potential misuse of these models.
