- Summary
- bagisto has a Cross Site Scripting (XSS) vulnerability in TinyMCE Image Upload (SVG)
- Details
-
Summary
In Bagisto v2.3.7, the TinyMCE image upload functionality allows an attacker with sufficient privileges (e.g. admin) to upload a crafted SVG file containing embedded JavaScript. When viewed, the malicious code executes in the context of the admin/user’s browser.
Details
The underlying problem is that SVG is XML/markup, so when it is uploaded and then directly rendered or embedded, script or event handlers within are allowed to run unless sanitized. In Bagisto, the integration of TinyMCE’s image upload (or media manager) may accept SVG files without sanitizing or rejecting unsafe content. When the SVG is later included (inline or via object/embed) in content displayed in admin or UI, the browser may execute the script portion of the SVG. The application might not validate the file content (i.e. inspect the SVG XML) or strip
