CVE-2026-47119
Full vulnerability record from the local CVENow database.
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.

Los atacantes pueden colocar un archivo SVG manipulado que contiene etiquetas de script en cualquier ruta legible por el proceso agent-zero y atraer a un usuario autenticado al endpoint image_get, haciendo que el navegador ejecute el script malicioso, robe la cookie csrf_token y realice llamadas a la API no autorizadas en nombre de la víctima."
