Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Roller 6.1.5 中存在的 XML 外部实体（XXE）引用限制不当漏洞，允许博客管理员通过导入特制的 OPML 文档，读取 Roller 进程有权访问的文件，并探测内部网络地址。原因在于书签导入解析器未禁用外部实体解析。无需进行任何非默认配置即可触发该漏洞，该漏洞可通过管理员的书签导入操作访问。建议用户升级至 Apache Roller 6.1.6 或更高版本，该版本采用加固的解析器，禁用了外部实体和文档类型声明（DTD）。

Vulnerability Title
Apache Roller: XML external entity processing in OPML bookmark import
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5 allows a weblog administrator to read files readable by the Roller process and reach internal network addresses by importing a crafted OPML document, because the bookmark import parser does not disable external entity resolution. No non-default configuration is required; the import is reached through the administrator bookmark-import action. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which uses a hardened parser that disables external entities and document type declarations.
