Stored XSS via executable SVG asset responses
Published Jan 10, 2022 · Updated Sep 17, 2024
Stored XSS in Directus 9.0.0-alpha.4 through 9.4.1 allows remote authenticated users to run JavaScript via uploaded SVG files. The media upload path stores attacker-supplied SVG content, and the asset response lacked a default CSP that blocks its scripts. Low-privileged upload access and a victim opening the image URL are required, exposing data and actions available to the victim's session.
