CVE-2018-8007

Apache CouchDB administrative users can configure the database server via
HTTP(S). Due to insufficient validation of administrator-supplied
configuration settings via the HTTP API, it is possible for a CouchDB
administrator user to escalate their privileges to that of the operating
system’s user that CouchDB runs under, by bypassing the blacklist of
configuration settings that are not allowed to be modified via the HTTP
API. This privilege escalation effectively allows an existing CouchDB admin
user to gain arbitrary remote code execution, bypassing already disclosed
CVE-2017-12636. Mitigation: All users should upgrade to CouchDB releases
1.7.2 or 2.1.2.
