CVE-2026-82383— Apache Roller: Anonymous setup action allows frontpage configuration tampering
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 中存在关键功能缺少身份验证漏洞。未认证的远程攻击者可以持久修改任何已部署实例上的站点全局配置值（即首页博文选择），因为在安装完成后，其配置操作仍可通过匿名访问，且在未进行权限校验的情况下直接写入配置。无需启用任何可选功能或非默认配置即可利用此漏洞，可能导致站点公共首页重定向或无法正常显示，但管理员可通过管理后台恢复。建议用户升级至 Apache Roller 6.1.6 或更高版本，该版本已将全局配置的写权限限制为仅限管理员操作。

Vulnerability Title
Apache Roller: Anonymous setup action allows frontpage configuration tampering
Source: CVE Program / CVE List V5
Vulnerability Description
Missing Authentication for Critical Function in Apache Roller 6.1.5 allows an unauthenticated remote attacker to persistently change a site-global configuration value (the frontpage weblog selection) on any installed instance, because the setup action remains anonymously reachable after installation and persists configuration without an authorization check. No optional feature or non-default configuration is required; the result can redirect or break the site's public frontpage, with administrative recovery available. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which restricts the write to global administrators.
