Several RCE vulnerabilities have been found and corrected in 2.14.15 :

CVE-2019-16530: An attacker with elevated privileges can upload a
specially crafted file. That file can contain commands that will be
executed on the system, with the same privileges as the user running
the server.

CVE-2019-15893: A Remote Code Execution vulnerability has been
discovered in Nexus Repository Manager requiring immediate action. The
vulnerability allows for an attacker with administrative access to
NXRM to create repostories that can grant access to read/execute
system data outside the scope of NXRM.

CVE-2019-5475: A vulnerability has been found that can allow user's
with administrative privileges to run processes on the target server,
that the nxrm os user has access to.");
