While no POP chain (a sequence of gadgets used to achieve code execution) is present in the software itself, the presence of a POP chain via another installed plugin or theme could enable the deletion of arbitrary files, retrieval of sensitive data, or remote code execution.
Recommendations Update to a version newer than 1.1.8.
