SCA: security update for horovod (GHSA-mf8f-x4r3-jm8c)

critical Tenable Cloud Security Plugin ID 477670

Description

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

 - Horovod thru 0.28.1 contains an insecure deserialization vulnerability (CWE-502) in its KVStore HTTP
 server component. The KVStore server, used for distributed task coordination, lacks authentication and
 authorization controls, allowing any remote attacker to write arbitrary data via HTTP PUT requests. When a
 Horovod worker reads data from the KVStore (via HTTP GET), it deserializes the data using
 cloudpickle.loads() without verifying its source or integrity. An attacker can exploit this by sending a
 malicious pickle payload to the server before the legitimate data is written, causing the victim worker to
 deserialize and execute arbitrary code, leading to remote code execution. (CVE-2026-31234)

Solution

There is no known solution at this time.
