CVE-2026-55466 Details
Description
Snipe-IT is an IT asset/license management system. Prior to 8.6.2, UploadFileRequest sanitizes SVG content only when PHP finfo reports image/svg+xml and UploadedFilesController serves attachments inline without using StorageHelper::allowSafeInline(), allowing a low-privilege user to upload active XHTML or XML content that is later served same-origin and executes JavaScript in a viewer’s browser. This issue is fixed in version 8.6.2.
A stored cross-site scripting vulnerability has been identified in Snipe-IT versions prior to 8.6.2. The issue arises in the file upload functionality, where SVG content is not properly sanitized before being served inline. This flaw allows a low-privilege user to upload a file containing active JavaScript, which is then executed in the context of the user's browser. The vulnerability exists because the application only sanitizes SVG files when the PHP file information function recognizes the MIME type as 'image/svg+xml'. Instead, a user can upload an XHTML or XML file that bypasses this check, leading to the execution of injected scripts.
Users are advised to upgrade to Snipe-IT version 8.6.2 or later, where this vulnerability has been patched.
