Description

According to its self-reported version number, the instance of Atlassian JIRA hosted on the remote web server is prior to 7.12.3. It is, therefore, affected by an authentication bypass vulnerability in its inline-create REST component. An authenticated, remote attacker can exploit this, by sending crafted HTTP requests, to bypass authentication and set the reporter on Jira issues.
