Hello, we was reported that jQuery 2.1.4, has Cross-site Scripting (XSS) vulnerability and our system can be misused. For more details https://www.cvedetails.com/vulnerabi...ery-2.1.4.html

There are a sample jQuery 2.1.4: .../client/espo.min.js Might be it would be good to use more secure versions?

Good day
Latest jquery, version 2 still have some vulnerabilities

and remediation is updating to the latest jquery, version 3, but the whole project is written on jquery, version 2 as I understand.

Any idea how this vulnerability can be resolved?

In the most cases, these vulnerabilities are not affected to EspoCRM v6+.
The new release v7.0.0 will have updated jquery to version 3.5.

Can you re-test it on v6 and seem it that is the case Chukach

I suggest just ignoring them on v6. They are not actual in EspoCRM context.

Here is a post that was made yesterday on this topic.

It does not relate to this topic.

[espcrm]

Although it not related to this topic itself... but the vulnerability exist in the current 'stable' right?

My version at the moment is 6.1.2, they tested on v6.1.6 which I assume affect every version before then... current stable version is 6.1.8 which could have fixed these flaw. I sorta want to try on my own system to see.

I guess the only good point for us is we don't activate portal so not too many people know about our EspoCRM installation.

Reading through the article the score is quite low so that in one way a good sign, unlike Akaunting which scored in 8.x range.

CVE-2021-3539 (CVSS score: 6.3) - Persistent XSS flaw in EspoCRM v6.1.6

Good news is it seem to be fixed? "For all of these issues, updating to the latest versions of the affected applications will resolve them"

A vulnerability in a library does not mean vulnerability in the application that uses that library.
