An information disclosure vulnerability exists in OneLogin AD Connector versions prior to 6.1.5 via the /api/adc/v4/configuration endpoint. An attacker with access to a valid directory_token—which may be retrievable from host registry keys or improperly secured logs—can retrieve a plaintext response disclosing sensitive credentials. These may include an API key, AWS IAM access and secret keys, and a base64-encoded JWT signing key used in the tenant’s SSO IdP configuration.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
