CWE-287

Description

Backstage is an open framework for building developer portals. Prior to 0.4.20, the @backstage/plugin-auth-backend-module-oidc-provider package is affected by improper authentication in the oidc provider. Deployments using OIDC email-based identity resolution with a provider that permits unverified email addresses may allow an authenticated provider user to assume another catalog identity. This may grant access and permissions associated with that user. No direct availability impact is demonstrated. This issue is fixed in version 0.4.20.

Affected configurations

• linuxfoundation backstage\/plugin-auth-backend-module-oidc-provider (< 0.4.20) • linuxfoundation backstage (< 1.54.6)
