CVE-2026-58659

A flaw was found in PyTorch Lightning. This vulnerability allows attackers to achieve remote code execution by crafting malicious checkpoint files. These files exploit a weakness in the loadstate function, which imports and executes attacker-controlled module names from checkpoint instantiator...

CVE-2026-58659 PyTorch Lightning Arbitrary Code Execution via _instantiator Hyperparameter

PyTorch Lightning through 2.6.5, fixed in commit d710d68, contains a remote code execution vulnerability in the loadstate function that imports and executes attacker-controlled module names from checkpoint instantiator hyperparameters. Attackers can craft malicious checkpoint files that bypass...
