Summary
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.
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

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.
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2022-0087 has a CVSS score of 7.1 (High). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.0.2); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2022-0087? CVE-2022-0087 is a high-severity cross-site scripting (XSS) vulnerability in @keystone-6/auth (npm), affecting versions < 1.0.2. It is fixed in 1.0.2. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is CVE-2022-0087? CVE-2022-0087 has a CVSS score of 7.1 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which packages are affected by CVE-2022-0087?
@keystone-6/auth(npm) (versions < 1.0.2)@keystone-next/auth(npm) (versions <= 37.0.0)
- Is there a fix for CVE-2022-0087? Yes. CVE-2022-0087 is fixed in 1.0.2. Upgrade to this version or later.
- Is CVE-2022-0087 exploitable, and should I be worried? Whether CVE-2022-0087 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2022-0087 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2022-0087? Upgrade
@keystone-6/authto 1.0.2 or later.
