Ray prior to 2.56.0 contains an unsafe deserialization vulnerability in the WebDataset reader that allows attackers to achieve remote code execution by supplying a malicious tar archive to the read_webdataset() function. The _default_decoder() function in webdataset_datasource.py unconditionally calls pickle.loads() on tar entries with .pkl\/.pickle extensions and torch.load() with weights_only=False on .pt\/.pth entries, executing arbitrary code inside Ray remote workers on every worker that processes the malicious archive.<\/p>\n","protected":false},"excerpt":{"rendered":"
