This Third-Party Dependency vulnerability, with a CVSS Score of 7.5 and a CVSS Vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H allows an unauthenticated attacker to expose assets in your environment susceptible to exploitation which has no impact to confidentiality, no impact to integrity, high impact to availability, and requires no user interaction. Atlassian recommends that Jira Software Data Center and Server customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions: * Jira Software Data Center and Server 9.11: Upgrade to a release greater than or equal to 9.11.3 See the release notes. You can download the latest version of Jira Software Data Center and Server from the download center.

Hi, 

Atlassian support informed us, that this would also be fixed in 9.4.14. similar to the other CVEs, however I don't see it as a fix version yet.

Please clarify.

Dear Atlassian team,

Please could you clarify the sentence: "This High severity Third-Party Dependency vulnerability was introduced in versions 8.20.0,.."

For me it is not clear if the vulnerability was in introduced in version 8.20.0 and remain in all later  8.20.x versions

or

if the vulnerability was only affects to version 8.20.0.

Is the only fix available other than 9.11.3? Is not any planned fixing for 8.20.X?

As a suggestion try to avoid the words " vulnerability was introduced" and use explicitly " vulnerability affected to". This will avoid misunderstandings.

Looking forward to your feedback,

Thanks in advance,

Cheers,

Roberto Correa
