CVE-2026-82378— Apache Roller: OAuth authorization endpoint trusts request-supplied identity
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 的 OAuth 1.0a 授权端点存在不正确的授权逻辑漏洞。该漏洞允许远程未认证攻击者在获取到已配置的全站消费者（site-wide consumer）的待处理请求令牌（request token）后，通过提交一个未签名的授权请求，将该令牌绑定到任意用户账户（包括管理员账户）。 该端点从请求中提供的值派生授权身份，而不是使用已认证的会话状态。只有配置了 OAuth 1.0a 全站消费者的安装实例才受影响，且利用该漏洞需要攻击者知晓其中一个待处理的请求令牌。 建议用户升级至 A

Vulnerability Title
Apache Roller: OAuth authorization endpoint trusts request-supplied identity
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect Authorization in the OAuth 1.0a authorization endpoint of Apache Roller 6.1.5 allows an unauthenticated remote attacker who learns an outstanding request token for a configured site-wide consumer to bind that token to an arbitrary user account, including an administrator, by submitting an unsigned authorization request. The endpoint derives the authorizing identity from a request-supplied value rather than the authenticated session. Only installations that configure an OAuth 1.0a site-wide consumer are affected, and exploitation requires knowledge of one of its outstanding request tokens. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which binds authorization to the logged-in session.
