Software development and collaboration solutions provider Atlassian on Wednesday informed customers that it has patched a critical code execution vulnerability affecting some of its Jira products.

According to Atlassian, security researcher Harrison Neal discovered that Jira Data Center - including Software Data Center and Core Data Center - and Jira Service Management Data Center software development products are affected by a critical flaw related to missing authentication for the Ehcache RMI network service.

"While Atlassian strongly suggests restricting access to the Ehcache ports to only Data Center instances, fixed versions of Jira will now require a shared secret in order to allow access to the Ehcache service," Atlassian said in a security advisory.

The company pointed out that non-Data Center instances of Jira Server and Jira Service Management are not impacted, and neither are Jira Cloud and Jira Service Management Cloud customers.

Jira Data Center users have been advised to update their installations to versions 8.5.16, 8.13.8 or 8.17.0.

Jira Service Management Data Center users can patch the vulnerability by ensuring that they are running versions 4.5.16, 4.13.8 or 4.17.0.
