Stored XSS via unsanitized SVG uploads

Published Oct 16, 2025 · Updated Oct 16, 2025

Stored XSS in Bagisto 2.3.7 allows remote authenticated users to execute JavaScript in a viewer's browser through a crafted SVG upload. The TinyMCE upload path stores SVG markup without rejecting or neutralizing embedded scripts and event handlers, then serves it for browser rendering. Administrative upload access and a second administrator or editor viewing the content are required; the script can hijack sessions or perform unauthorized actions.
