@backstage/plugin-auth-backend is an A Backstage backend plugin that handles authentication

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). It allows a malicious actor to trick another user into visiting a vulnerable URL, which can potentially allow the attacker to exfiltrate access tokens or other secrets from the user's browser. The default CSP header does prevent this attack, but it is expected that some deployments have these policies disabled due to incompatibilities.

How to fix Cross-site Scripting (XSS)?

Upgrade @backstage/plugin-auth-backend to version 0.4.9 or higher.
