Frequently Asked Questions
1
What must an attacker be able to do to exploit this issue?
The attacker needs to submit an SVG payload to the /api/v2/ai/sessions API using a data:image/svg+xml;base64 format. The embedded script executes when that content is rendered in the assistant window.
2
Who is exposed to the malicious script?
Users who render the attacker-controlled SVG content in the assistant window are exposed. The issue can execute JavaScript in that rendering context and alter displayed content.
