Description
Agent Zero before version 1.15 contains a stored cross-site scripting vulnerability that allows attackers to execute arbitrary JavaScript in the application origin by serving SVG files through the image_get API endpoint without Content-Security-Policy, X-Content-Type-Options, or Content-Disposition headers. Attackers can place a crafted SVG file containing script tags in any path readable by the agent-zero process and lure an authenticated user to the image_get endpoint, causing the browser to execute the malicious script, steal the csrf_token cookie, and perform unauthorized API calls on behalf of the victim.
