## Technical details

The vulnerability is a stored cross-site scripting (CWE-79) flaw in Strapi versions 3.6.10 and earlier, triggered through the file upload functionality. An authenticated administrator can upload a file containing malicious JavaScript that is not properly sanitized, causing the script to execute when other privileged users view or interact with the uploaded file. The attack requires an authenticated account with administrative privileges and user interaction (viewing the malicious content), but once stored, the payload persists and affects multiple users. No patch information is provided in the available advisory data.
