Unknown · File Thingie · CVE-2026-30579
**Name of the Vulnerable Software and Affected Versions**
File Thingie version 2.5.7
**Description**
File Thingie version 2.5.7 is susceptible to Cross Site Scripting (XSS). A malicious user can exploit the "upload file" functionality by uploading a file with a specially crafted file name to trigger a Javascript payload. The vulnerable functionality involves the processing of uploaded files and their associated names. The `filename` is not properly sanitized before being used in a web page, allowing for the injection of malicious scripts.
**Recommendations**
Update to a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict the types of files that can be uploaded. Sanitize the `filename` before using it in a web page.
