GHSA-hrgx-7j6v-xj82

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 If for some reason you cannot upgrade the dependencies in software, you could alternatively

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