# IBM Langflow OSS: authenticated users can run arbitrary code remotely

IBM Langflow OSS versions 1.0.0 through 1.12.3 fail to neutralize special elements in code, which lets a remote attacker who has a valid account execute arbitrary code. The NVD rating is high, with a CVSS score of 8.8.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Langflow version, for example with `pip show langflow`, and compare it to the affected range `1.0.0` through `1.12.3`.
- Confirm whether the instance is reachable from the internet and who holds accounts on it.

## Fix

- Move to a Langflow OSS release newer than `1.12.3`; the sources do not name the exact fixed version.

## From the sources

IBM Langflow OSS 1.0.0 through 1.12.3 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of special elements used in code.
