What is CVE-2026-59078?

Edito CMS has a vulnerability that allows authenticated attackers to exploit the avatar upload functionality, leading to stored Cross-Site Scripting (XSS). This vulnerability enables attackers to inject arbitrary HTML and JavaScript code into the website. When a user accesses a URL associated with the modified avatar, the injected code is executed, potentially compromising user data and system integrity. As a mitigation measure, Edito has released version 5.10.2607, which addresses this issue, along with hotfixes for affected older versions, including 5.8.
