CVE-2026-94611 · Severity: high · CVSS 8.1 · Published 2026-09-24

authentik is an open-source identity provider used for managing user access and authentication across organizations. A flaw in its API serializers causes stored credentials—including secrets for SMS/email delivery, API keys for external services, and authentication tokens—to be exposed to users with view permissions, even if they lack authorization to change configurations or access secrets. This allows credential theft by accounts with limited administrative access.

## Technical details

API serializers in authentik versions prior to 2026.2.7, 2026.5.7, and 2026.8.2 return sensitive credential data in API responses to any account holding view permission on affected configurations, regardless of change/secret-read authorization.

Exploitation requires network access and a valid authentik account with view-level permissions on target configurations.
