Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker to inject malicious JavaScript into the API key overview, which can then execute when another user views that section. It affects all authenticated users before version 2.0.0, as there were no permissions to restrict access, but if a user is the only one using Gokapi, they are not at risk.

Technical Description

Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. By renaming the friendly name of an API key, an authenticated user could inject JS into the API key overview, which would also be executed when another user clicks on his API tab. Prior to version 2.0.0, there was no user permission system implemented, therefore all authenticated users were already able to see and modify all resources, even if end-to-end encrypted, as the encryption key had to be the same for all users of versions prior to 2.0.0. If a user is the only authenticated user using Gokapi, they are not affected. This issue has been fixed in v2.0.0. A workaround would be to not open the API page if it is possible that another user might have injected code.

CVE-2025-48494Medium

An attacker can exploit a flaw in Gokapi to upload a file with malicious JavaScript in its name, which runs every time the upload list is viewed, potentially allowing them to execute harmful actions on the server. This vulnerability primarily affects systems before version 2.0.0, where all authenticated users could access and modify all files, making it easier for an attacker if multiple users are present.
