CVE-2026-82375— Apache Roller: Server-side request forgery via entry trackback and enclosure URLs

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 中存在服务器端请求伪造（SSRF）漏洞。具有网日志条目编辑权限的已认证用户，可以通过遗留的出站 Trackback 和条目附件（enclosure）处理机制，向攻击者指定的目标发起出站 HTTP 请求。尽管 Trackback 控制功能在标准用户界面中已被隐藏，但其对应的操作仍可直接访问；而附件路径仅在作者提供附件 URL 时相关。该漏洞无需任何非默认服务器配置，且默认的 Trackback 允许列表为空，意味着允许所有目标地址。此类请求可达回环地址（loopback）及私有

Vulnerability Title
Apache Roller: Server-side request forgery via entry trackback and enclosure URLs
Source: CVE Program / CVE List V5
Vulnerability Description
Server-Side Request Forgery (SSRF) in Apache Roller 6.1.5 allows an authenticated user with entry-editing rights on a weblog to cause outbound HTTP requests to attacker-chosen destinations through legacy outbound Trackback and entry enclosure handling. The Trackback control is hidden in the standard UI, but its action remains directly reachable; the enclosure path is relevant only when an author supplies an enclosure URL. No non-default server configuration is required, and the default empty Trackback allow-list permits all destinations. Requests can reach loopback and private-network addresses, while enclosure handling exposes response status, content type, and length. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes the outbound trackback action and stops dereferencing enclosure URLs.
