  • This plugin stores a list of files to be deleted in an option, meaning anybody able to set the value of serialised options can delete arbitrary files. However WordPress doesn’t allow admins to modify serialised options so this shouldn’t be considered a vulnerability: modifying this data would either require direct access to the database or a SQL injection via another vulnerability.
