For this release, we anticipate the following introductions in your environments. Major features are documented in the Blend Knowledge Base accessible at help.blend.com. If that resource does not answer your question, please reach out to Blend Support.


Announcements (2)


(New) SAML Key Encryption Update Required

We are deprecating support for RSA 1.5 (RSA_PKCS1_PADDING) key encryption for SAML assertions, which will be fully removed by October 1st, 2026. This change is driven by a Node.js 22+ security fix for the Marvin Attack vulnerability (CVE-2023-46809), which removes support for RSA 1.5 padding in the decryption path, meaning any SAML assertions still using this method will fail to decrypt. IdP administrators must update their SAML key encryption method from RSA 1.5 to RSA-OAEP (xmlenc#rsa-oaep-mgf1p) in their Identity Provider's SAML integration or Service Provider (SP) connection settings by October to avoid disruption to borrower SAML-based authentication. This update is typically carried out by your institution's IT team. If you have questions or need assistance, please reach out to your Blend representative or open a support ticket.


Note: Update steps may vary depending on your IdP (e.g., Okta, Azure AD, PingFederate, OneLogin, etc.). Refer to your IdP's documentation or contact their support team for specific instructions.


Encompass Lower Environment Migration

ICE is in the process of migrating customers’ Encompass lower environments over a period of time. If you are scheduled for migration, please be aware of the following important steps to ensure continued connectivity with Blend:


What You Need to Do:

Notify Blend Support at least 10 days in advance of your scheduled migration. This lead time is necessary for Blend to prepare and reestablish connectivity between your Encompass Beta and Blend Beta environments.


If you have received a migration notification from ICE and do not intend to delay the migration, please notify Blend Support immediately to ensure your systems remain connected.


For additional details, please refer to ICE's official documentation here:
