Overview
Affected versions of this package are vulnerable to Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') when uploading an avatar image, due to a missing security header. An attacker can inject code into an SVG image to gain access to the victim's account by executing the script during rendering. This is exploitable if the victim directly opens the malicious image in the browser and has a single active session in ZITADEL.
Workaround
This vulnerability can be mitigated by adding the following response header (e.g. within your WAF or reverse proxy) to the assets path ($ZITADEL_DOMAIN/assets/v1/*):
Content-Security-Policy: default-src 'none';img-src 'self';object-src 'none';style-src 'self';media-src 'none';frame-src 'none';frame-ancestors 'none';font-src 'self';script-src 'self';manifest-src 'self';connect-src 'self'
