CVE-2024-42054Network attack vector

HTML injection via unrestricted file upload

Published Jul 28, 2024 · Updated Oct 28, 2024

Unrestricted file upload in Cervantes 0.5-alpha and earlier allows remote authenticated users to inject HTML through crafted files. The upload functionality accepts files without validating their nature or constraining HTML content, allowing browser-rendered markup to enter the application. Exploitation requires an authenticated upload and another user's interaction with the file; published evidence bounds the impact to HTML injection.
