SCA: security update for ray (GHSA-mw35-8rx3-xf9r)

high Tenable Cloud Security Plugin ID 440810

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Ray is an AI compute engine. From version 2.54.0 to before version 2.55.0, Ray Data registers custom Arrow
 extension types (ray.data.arrow_tensor, ray.data.arrow_tensor_v2, ray.data.arrow_variable_shaped_tensor)
 globally in PyArrow. When PyArrow reads a Parquet file containing one of these extension types, it calls
 __arrow_ext_deserialize__ on the field's metadata bytes. Ray's implementation passes these bytes directly
 to cloudpickle.loads(), achieving arbitrary code execution during schema parsing, before any row data is
 read. This issue has been patched in version 2.55.0. (CVE-2026-41486)

Solution

Update the ray library and its related packages to version 2.55.0 or later.
