CVE-2021-32735 (GCVE-0-2021-32735)

Vulnerability from cvelistv5 – Published: 2021-07-02 14:45 – Updated: 2024-08-03 23:33

Title

Cross-site scripting (XSS) from field and configuration text displayed in the Panel

Summary

Kirby is a content management system. In Kirby CMS versions 3.5.5 and 3.5.6, the Panel's `ListItem` component (used in the pages and files section for example) displayed HTML in page titles as it is. This could be used for cross-site scripting (XSS) attacks. Malicious authenticated Panel users can escalate their privileges if they get access to the Panel session of an admin user. Visitors without Panel access can use the attack vector if the site allows changing site data from a frontend form. Kirby 3.5.7 patches the vulnerability. As a partial workaround, site administrators can protect against attacks from visitors without Panel access by validating or sanitizing provided data from the frontend form.
