Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
pytorch-lightning is a lightweight PyTorch wrapper for ML researchers. Scale your models. Write less boilerplate.
Affected versions of this package are vulnerable to Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') via the _load_state function that imports and executes module names specified in checkpoint _instantiator hyperparameters. An attacker can achieve arbitrary code execution by providing a malicious checkpoint file that is loaded through the load_from_checkpoint function.
