CVE-2025-65012 (GCVE-0-2025-65012)

Vulnerability from cvelistv5 – Published: 2025-11-18 22:44 – Updated: 2025-11-19 17:06

Summary

Kirby is an open-source content management system. From versions 5.0.0 to 5.1.3, attackers could change the title of any page or the name of any user to a malicious string. Then they could modify any content field of the same model without saving, making the model a candidate for display in the "Changes" dialog. If another authenticated user subsequently opened the dialog in their Panel, the malicious code would be executed. This vulnerability affects all Kirby 5 sites that might have potential attackers in the group of authenticated Panel users or that allow external visitors to update page titles or usernames. The attack requires user interaction by another Panel user and cannot be automated. This issue has been patched in version 5.1.4.

Vulnerability from github – Published: 2025-11-18 18:01 – Updated: 2025-11-19 14:22

Summary

Kirby CMS has cross-site scripting (XSS) in the changes dialog

Details

TL;DR

This vulnerability affects all Kirby 5 sites that might have potential attackers in the group of authenticated Panel users or that allow external visitors to update page titles or usernames.

The attack requires user interaction by another Panel user and cannot be automated.

Introduction

Cross-site scripting (XSS) is a type of vulnerability that allows to execute any kind of JavaScript code inside the Panel session of the same or other users. In the Panel, a harmful script can for example trigger requests to Kirby's API with the permissions of the victim.

Such vulnerabilities are critical if you might have potential attackers in your group of authenticated Panel users. They can escalate their privileges if they get access to the Panel session of an admin user. Depending on your site, other JavaScript-powered attacks are possible.

Impact

The "Changes" dialog in the Panel displays all content models (pages, files, users) with changed content, i.e. with content that has not yet been published. Each changed model is listed with its preview image/icon and its title/name.

Attackers could change the title of any page or the name of any user to a malicious string. Then they could modify any content field of the same model without saving, making the model a candidate for display in the "Changes" dialog. If another authenticated user subsequently opened the dialog in their Panel, the malicious code would be executed.

Patches

The problem has been patched in Kirby 5.1.4. Please update to this or a later version to fix the vulnerability.

In the patch release, we have added the required escaping code to signal to the browser the intent of displaying plain text instead of code in the places where the model titles are rendered.

Severity ?

5.1 (Medium)
