What is CVE-2026-26272?

HomeBox, an inventory and organization application, is susceptible to a stored cross-site scripting vulnerability due to insufficient validation of uploaded files. Prior to version 0.24.0-rc.1, it allows authenticated users to upload harmful HTML or SVG files that can include executable JavaScript. These malicious attachments can be accessed through direct links, potentially resulting in the execution of embedded scripts in the context of the application's origin whenever a user interacts with these files. This critical flaw underscores the need for proper file validation measures to mitigate security risks in web applications.

Affected Version(s)

homebox < 0.24.0-rc.1
