CWE ID 79

Summary

CVE-2023-46252 is a Cross-Site Scripting (XSS) vulnerability affecting Squidex, an open-source headless CMS and content management hub. The vulnerability is present in versions that lack origin verification in a postMessage handler. The issue arises from the editor-sdk.js file, which defines three class-like functions: SquidexSidebar, SquidexWidget, and SquidexFormField. These functions use a global message event listener to perform actions based on the type of received message. However, the SquidexFormField class is vulnerable as it registers a callback function that can be exploited by passing an attacker-controlled value, leading to XSS. Organizations using affected versions of Squidex are advised to update to a patched version to remediate the vulnerability. The vulnerability has a medium severity rating with low impact on integrity and confidentiality, requiring user interaction over a network connection for exploitation.
