CVE-2026-123374— Apache Roller: Deserialization of untrusted data in weblog update ping responses

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 存在“不可信数据反序列化”漏洞。当 Roller 发送 weblog 更新通知（ping）时，其 XML-RPC 客户端会反序列化 ping 目标响应中包含的 Java 对象数据，因此能够控制该响应的攻击者可在 Roller 服务器进程中执行任意代码。此漏洞影响 Apache Roller 4.0 至 6.1.6 版本。建议用户升级至 6.1.7 版本，该版本已移除了不安全的反序列化操作。

Vulnerability Title
Apache Roller: Deserialization of untrusted data in weblog update ping responses
Source: CVE Program / CVE List V5
Vulnerability Description
Deserialization of Untrusted Data vulnerability in Apache Roller. When Roller sends a weblog update ping, its XML-RPC client deserializes Java object data contained in the ping target's response, so a party that controls that response can run code in the Roller server process. This issue affects Apache Roller from 4.0 through 6.1.6. Users are recommended to upgrade to version 6.1.7, which removes the unsafe deserialization.
