vulnerability as referenced in the CONFSERVER-79017 advisory.

  - *Summary* A remote attacker who can connect to the Hazelcast service, running on port 5801 (and
    potentially 5701), is able to execute arbitrary code on all the nodes in a Confluence Data Center through
    Java deserialization. *Vulnerability Details* Confluence Data Center uses the third-party software
    Hazelcast, which is vulnerable to Java deserialization attacks (CVE-2016-10750). Hazelcast provides
    functionality needed to run Confluence Data Center as a cluster. A remote, unauthenticated attacker can
    exploit this vulnerability by sending a specially crafted JoinRequest, resulting in arbitrary code
    execution. The affected versions are from 1.3.0 before 7.4.17, from 7.13.0 before 7.13.7, from 7.14.0
    before 7.14.3, from 7.15.0 before 7.15.2, from 7.16.0 before 7.16.4, from 7.17.0 before 7.17.4, and from
    7.18.0 before 7.18.1. (atlassian-CONFSERVER-79017)
