CVE-2026-105153— Apache Roller: XML external entity processing in AtomPub entry parsing

Quick assessment

Affected
Apache Software Foundation Apache Roller
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Roller 4.0 至 6.1.6 版本中存在 XML 外部实体引用限制不当的漏洞。该漏洞允许没有博客权限的已认证用户，通过向 AtomPub 端点提交特制的 Atom 条目，读取 Roller 进程可访问的文件，并诱导服务器向攻击者指定的目标发起出站 HTTP 请求。该漏洞的成因在于：Atom 条目正文在解析时使用了允许外部参数实体和外部 DTD 子集的解析器配置，且解析操作在执行任何博客级别的授权检查以及任何关于 AtomPub 功能是否启用的检查之前就已经完成。因此，在默认安装配置下，该端点对

Vulnerability Title
Apache Roller: XML external entity processing in AtomPub entry parsing
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Restriction of XML External Entity Reference in Apache Roller 4.0 through 6.1.6 allows an authenticated user with no weblog permissions to read files readable by the Roller process and cause the server to issue outbound HTTP requests to attacker-chosen destinations, by submitting a crafted Atom entry to the AtomPub endpoint. The entry body is parsed with a parser configuration that permits external parameter entities and external DTD subsets, and the parse happens before any per-weblog authorization check and before any check of whether the AtomPub feature is enabled, so the endpoint is reachable by any authenticated account on a default installation. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which parses AtomPub entries with a hardened XML configuration and rejects AtomPub requests while the feature is disabled.
