Description

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to version 2.62.2, the SPA index page in File Browser is vulnerable to Stored Cross-Site Scripting (XSS) via admin-controlled branding fields. An admin who sets branding.name to a malicious payload injects persistent JavaScript that executes for ALL visitors, including unauthenticated users. This issue has been patched in version 2.62.2.
