CVE-2026-25227Network attack vector

Authenticated code execution via context-key parameter injection

Published Feb 12, 2026 · Updated Feb 12, 2026

Code injection in affected authentik releases allows remote authenticated users to execute arbitrary code in the server container. The property-mapping and policy test endpoints pass request-supplied context keys to BaseEvaluator.wrap_expression, which joined weakly sanitized keys into a Python handler signature and accepted equals-sign default expressions. Either delegated Can view Property Mapping or Can view Expression Policy permission is sufficient to read the database and environment variables and take over the instance.
