CVE-2024-10190

Unauthenticated Remote Code Execution in ElasticRendezvousHandler in horovod/horovod

Published Mar 20, 2025 CVSS 3.0 · 9.8 Critical EPSS 1.1% KEV · Not listed
Description
Horovod versions up to and including v0.28.1 are vulnerable to unauthenticated remote code execution. The vulnerability is due to improper handling of base64-encoded data in the `ElasticRendezvousHandler`, a subclass of `KVStoreHandler`. Specifically, the `_put_value` method in `ElasticRendezvousHandler` calls `codec.loads_base64(value)`, which eventually invokes `cloudpickle.loads(decoded)`. This allows an attacker to send a malicious pickle object via a PUT request, leading to arbitrary code execution on the server.
