Reflected cross-site scripting (XSS) vulnerability
This security advisory relates to a capability for an attacker to exploit a reflected cross-site scripting vulnerability when using the @keystone-6/auth package.
Impact
The vulnerability can impact users of the administration user interface when following an untrusted link to the signin or init page.
This is a targeted attack and may present itself in the form of phishing and or chained in conjunction with some other vulnerability.
Vulnerability mitigation
Please upgrade to @keystone-6/auth >= 1.0.2, where this vulnerability has been closed.
If you are using @keystone-next/auth, we strongly recommend you upgrade to @keystone-6.
Workarounds

- disable the administration user interface, or
- if using a reverse-proxy, strip query parameters when accessing the administration interface
