CVE-2024-28435Public exploitNetwork attack vector

Outbound HTTP requests via active SVG upload

Published Mar 25, 2024 · Updated Aug 26, 2024

Server-side request forgery in Twenty 0.3.0 allows remote attackers to trigger HTTP requests through a crafted SVG file upload. The file workflow stores and serves an SVG whose image xlink:href remains attacker-controlled, allowing an external resource load. Exploitation requires a user to upload and open the file in a new tab; the demonstrated consequence is an HTTP request to an attacker-selected endpoint.
