Ray < 2.56.0 Remote Code Execution

Synopsis

Ray < 2.56.0 Remote Code Execution

Description

According to its self-reported version number, Ray is prior to 2.56.0. Therefore, it may be affected by a Remote Code Execution due to the unsafe deserialization performed by the default decoder of ray.data.read_webdataset(), which calls pickle.loads() on .pickle / .pkl members and torch.load() with weights_only=False on .pt / .pth members of an attacker-supplied WebDataset TAR file.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Ray version 2.56.0 or later.
