Can I determine the version of Jira if I don't have an account?

[Kevin Dea]

I'm looking to see an instance of Jira that we have is vulnerable to JSDSERVER-14007  (https://jira.atlassian.com/browse/JSDSERVER-14007).  I'm not an admin or user on it so I can't log in, I just see the public URL.  Can I see what version it is the same way I can see the version of Confluence?

@Kevin Dea - welcome to the Atlassian Community, Kevin! 👋

One way to check the app version of a particular Jira instance is via Jira's API. This will work even if you're not logged into the Jira instance.

The rest endpoint is /rest/api/2/serverinfo

Example: (don't click)!

https://jira.totally-not-a-shell-company.xyz/rest/api/2/serverInfo

Fun fact, that REST endpoint works in Jira Cloud - any instances with URLs ending in atlassian.net. Not that you'd need to check for versions in Atlassian-hosted cloud instances.

Thanks!  That was exactly what I needed.
