Log4j critical vulnerability: CVE-2021-44228

Hi UiPath Team,

Would like to know if there is any update regarding the log4j vulnerability in UiPath products Orchestrator, Insights, AI center, action center.
We have found log4j files in Insights, so please suggest if there are any configurations or updates released to fix this.


Robots and Orchestrator uses NLog for logging which is a different framework.

Hi. Do you mean 21.4.1?

No, this isn’t specific to UiPath or their product. This is Log4j v2.14.1 and lower is affected. It was patched in 2.15.0

You’ll need to receive communication from UiPath on how a fix will be applied and whether they recommend an upgrade to Insights or manually upgrading Log4j. Each enterprise will need to make the determination on the urgency to fix the vulnerability and may opt to manually patch it if UiPath hasn’t communicated anything yet.

If you have not received direct communication from UiPath, I would suggest opening a ticket with support directly and/or reaching out to your CSM.

FYI another vulnerability for log4j was discovered CVE-2021-45046. It’s been addressed in the 2.16.0 as the original fix in 2.15.0 for CVE-2021-44228 was incomplete.

@Michelle_Yurovsky / @Forum_Staff - Can you Speak to this when UiPath has something further to communicate?

We have just posted an update! For all versions of Insights below 2021.10, please see UiPath Security Advisory CVE | UiPath. We have mitigation steps posted at UiPath Security Advisory CVE | UiPath. We appreciate the patience while we investigated and worked to confirm impact and mitigation. We understand that many of you have been waiting for this announcement.


Thanks @Michelle_Yurovsky !

Will a separate posting be made for CVE-2021-45046 or will that be updating on the same page as it mentions investigation is still on-going?

The same page there will be updated with any further announcements!


Does the 21.4.1 insights hotfix work on version 21.4.0 (on prem)

Hi @Anders_Sinding_Hadrup,

Welcome to the Community !

Yes, 21.4.1 Insights HotFix from GitHub is intended for use with Insights 21.4.0 (on-prem).

Hope that helps !

Thanks & Regards,


Hi @codemonkee ,

As per the details I have received from UiPath Support, with the latest patch they released as part of the mitigation steps we have now moved to Log4j Version 2.16.0 which was released by Log4j as a mitigation for CVE-2021-45046. So with the latest patch in place we should be protected from both CVE-2021-44228 & CVE-2021-45046.

Snip from the POM.xml in the Patch Provided by UiPath:



@Michelle_Yurovsky , are you looking into CVE-2021-45105 regarding insights and other products?

Hi Nithin,

Can we use Insights 19.10.7 hotfix for the insights version 20.4.1, please suggest

No, these are two different major.minor branches. You need the patch intended for your version. If one has not been released for 20.4 consider upgrading to 20.10, 21.x, etc. If unsure reach out to your Support or CSM.

Please see the links above in the thread, which contains recommendations for versions lower than 21.10.


The Security Advisor page linked about was updated to include this CVE.
