# CVE-2024-10190: Horovod Vulnerable to Command Injection

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 1.1% , percentile 66: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 66% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes horovod (PyPI) <= 0.28.1, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

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 putvalue method in ElasticRendezvousHandler calls codec.loadsbase64(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.

## Affected packages

- PyPI `horovod` <= 0.28.1 → fixed: none listed

## Affected products (CVE record)

- horovod horovod/horovod: unspecified <= latest

## Severity

- @huntr_ai CVSS 3.0: 9.8 `CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.12% probability of exploitation activity in the next 30 days; percentile 66.
