CVE-2026-82387— Apache Roller: Stored cross-site scripting via uploaded media content type

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.

在 Apache Roller 6.1.5 中存在“网页生成期间输入中和不当”（即跨站脚本攻击，XSS）漏洞。具有媒体上传权限的用户可以在 Roller 源站上存储并执行活跃内容，因为媒体上传功能信任上传时提供的内容类型，并以该类型将存储的文件返回给客户端。当受害者打开上传的文件时，会执行其中存储的脚本。媒体上传功能默认处于禁用状态；仅启用该功能的安装实例受影响，且一旦启用上传，已提供的类型限制无法阻止活跃内容的执行。建议用户升级至 Apache Roller 6.1.6 或更高版本，该版本会根据文件内容确定存储的

Vulnerability Title
Apache Roller: Stored cross-site scripting via uploaded media content type
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Apache Roller 6.1.5 allows a user with media-upload rights to store active content on Roller's origin, because the media upload feature trusts the upload-supplied content type and serves the stored file back with that type. A victim who opens the uploaded file executes the stored script. Media uploads are disabled by default; only installations that enable them are affected, and the shipped type restrictions do not block active content once uploads are on. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which derives the stored type from file content and serves non-image media as a download.
