# Address R vulnerability

On April 29, 2024, security researchers discovered a vulnerability that affects version 4.3 (and earlier) of the R programming language. The vulnerability allows a threat actor to arbitrarily execute code on targeted devices. The full details are [here](https://kb.cert.org/vuls/id/238194). 

This vulnerability is solved in R version 4.4, which is available on DataLab. You are strongly advised to upgrade the R version of workbooks you’re actively using from R version 4.2 to R version 4.4. 

### Steps to upgrade the R version in your workbooks

To adjust the settings of a workbook to use R version 4.4 instead of R version 4.2:

* Visit [www.datacamp.com/datalab](http://www.datacamp.com/datalab) (and sign in with your DataCamp account if needed)
* Open a workbook that you still plan to work on in the future.\
