CVE-2026-1466 Details
Description
Jirafeau normally prevents browser preview for text files due to the possibility that for example SVG and HTML documents could be exploited for cross site scripting. This was done by storing the MIME type of a file and allowing only browser preview for MIME types beginning with image (except for image/svg+xml, see CVE-2022-30110, CVE-2024-12326 and CVE-2025-7066), video and audio. However, it was possible to bypass this check by sending a manipulated HTTP request with an invalid MIME type like image. When doing the preview, the browser tries to automatically detect the MIME type resulting in detecting SVG and possibly executing JavaScript code. To prevent this, MIME sniffing is disabled by sending the HTTP header X-Content-Type-Options: nosniff.
A cross-site scripting vulnerability has been identified in Jirafeau versions 4.5.0 prior to 4.6.1. The issue arises because Jirafeau allows browser previews for certain file types, including SVG, which can be exploited to execute JavaScript. Although Jirafeau typically blocks previews for SVG files by enforcing strict MIME type checks, this protection can be bypassed. Attackers can upload files with manipulated MIME types that trick the server into allowing previews. When the preview is accessed, the browser's MIME type detection can inadvertently execute embedded JavaScript. This vulnerability takes advantage of improper input handling during file uploads, particularly with SVG files, which are known to pose scripting risks.
Users can update to Jirafeau versions 4.6.1 or later, where this vulnerability has been addressed.
