Path traversal in DeluxeThemes UserPro 5.1.10 and earlier allows remote attackers to read arbitrary server files without authentication. The userpro_fbconnect() function fails to confine a requested file path to its intended directory and returns the resolved file. Network access to the affected WordPress site is sufficient, and exposed files can contain credentials or other sensitive server data.
