# Apache Roller: CSRF lets a link create an administrator account

Link for people: https://infrastack.ai/live/CVE-2026-118411 (this .md is for agents)

Apache Roller accepts state-changing admin actions over GET without a valid request token, so a crafted link can make a logged-in administrator create a new admin account. An attacker who gets that account gains full control of the blogging server.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Apache Roller affected range not listed fixed no fixed version listed

## How to check

- Check the installed Apache Roller version in the deployed `WEB-INF/lib` or release files; affected range is `5.0.1` through `6.1.6`.
- Review the admin user list for accounts created recently that no one on the team recognises.

## Fix

- Apache Roller: upgrade to `6.1.7` or later, which requires POST and a valid token for data-changing actions.

## Timeline

- 2026-11-11T13:27:11+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118411

## From the sources

Cross-Site Request Forgery (CSRF) in Apache Roller 5.0.1 through 6.1.6 allows an unauthenticated attacker to create an administrator account if a logged-in Roller administrator opens a link that the attacker controls. The request-token check applied only to POST requests, and administrative actions also accepted GET requests. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which requires POST and a valid token for actions that change data.
