CVE-2026-105154: Apache Roller cross-site request forgery in Planet feed administration

CVE-2026-105154 · Severity: medium · CVSS 6.1 · Published 2026-11-11

Apache Roller is a blogging platform with a built-in Planet feed aggregator that collects and publishes content from multiple sources. A cross-site request forgery vulnerability allows an attacker to trick a logged-in administrator into fetching arbitrary URLs—including internal network addresses—and adding them as feed subscriptions. The attacker-controlled content then gets published to the aggregated feed, potentially exposing private information or injecting malicious content.

Technologies: Apache Roller. Vendors: Apache.

How to fix

  • Fixed in: Apache Roller 6.1.7 or later

Disable the Planet aggregator by setting planet.aggregator.enabled=false in roller-custom.properties if the feature is not in use.

Technical details

The Planet subscription add action accepts GET requests and lacks proper CSRF token validation, allowing an unauthenticated attacker to induce a global administrator to trigger the action via a crafted web page. The vulnerable code fetches the supplied URL and publishes any parseable feed content without further authentication. The fix requires POST requests with valid CSRF tokens for all Planet admin changes and disables the aggregator by default.
