No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The JIRA Workflow Designer Plugin in Atlassian JIRA Server before 6.3.0 improperly uses an XML parser and deserializer, which allows remote attackers to execute arbitrary code, read arbitrary files, or cause a denial of service via a crafted serialized Java object.
