CVE-2026-82385— Apache Roller: Weblog template include escapes the Velocity sandbox and reads classpath files

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 6.1.5 中存在“敏感信息暴露给未授权操作者”的漏洞。该漏洞允许博客管理员通过编写 Velocity 模板，利用 include 指令加载主题命名空间之外的类路径资源，从而读取应用程序类路径上的文件，包括包含敏感凭据的 Roller 配置文件。 Roller 将博客管理员视为不可信主体，并启用了 Velocity 沙箱机制；但 include 和 parse 指令并未受到该沙箱的限制。此问题不需要任何非默认配置即可利用，任何能够由管理员编写模板的博客均受影响。 建议用户升级到 Apac

Vulnerability Title
Apache Roller: Weblog template include escapes the Velocity sandbox and reads classpath files
Source: CVE Program / CVE List V5
Vulnerability Description
Exposure of Sensitive Information to an Unauthorized Actor in Apache Roller 6.1.5 allows a weblog administrator to read files on the application classpath, including Roller configuration files containing secrets, by authoring a Velocity template that uses an include directive to load a classpath resource outside the theme namespace. Roller treats weblog administrators as untrusted and enables a Velocity sandbox, but the include and parse directives are not confined by it. No non-default configuration is required; this affects any weblog whose administrator can author templates. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which confines includes to the active theme and removes classpath resource loading from weblog rendering.
