Critical (9.0) in filebrowser filebrowser. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in github.com/filebrowser/filebrowser/v2 2.62.2.
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 EPUB preview function in File Browser is vulnerable to Stored Cross-Site Scripting (XSS). JavaScript embedded in a crafted EPUB file executes in the victim's browser when they preview the file. This issue has been patched in version 2.62.2.
