CVE-2026-118411: Apache Roller CSRF allowing unauthenticated administrator account creation

CVE-2026-118411 · Severity: high · CVSS 8.8 · Published 2026-11-11

Apache Roller is a blogging platform that hosts community-managed blog content. A flaw in how it validates requests allows an attacker to trick a logged-in administrator into creating a new administrator account by visiting a malicious link. An attacker can thus gain administrative control over the blog platform and its content without needing valid login credentials.

Fixed in: Apache Roller 6.1.7 and later

Technical details

A cross-site request forgery vulnerability in Apache Roller versions 5.0.1 through 6.1.6 arises because request-token validation only applied to POST requests, while administrative actions also accepted GET requests. An unauthenticated attacker can craft a GET link that performs account-creation or other privileged actions; when a logged-in administrator clicks the link, the browser automatically sends the session cookie, allowing the attack to succeed. The fix in 6.1.7 enforces POST and valid CSRF tokens for all state-changing actions.

Affected products
