# SSO Connect On-Prem 17.1.1

This release focuses on security hardening of SAML processing and library currency to maintain a strong security posture with no configuration changes required for administrators.

#### What’s New <a href="#whats-new" id="whats-new"></a>

* Strengthened SAML validation pipeline with stricter response and assertion verification.
* Updated SAML library stack aligned with current Keycloak SAML release line.

#### Improvements <a href="#improvements.1" id="improvements.1"></a>

* Refined attribute extraction and validation to ensure correct audience/recipient/time enforcement across all SSO flows.
* General dependency hygiene to reduce vulnerability surface and align with supported versions.

#### Security & Bug Fixes <a href="#security-and-bug-fixes" id="security-and-bug-fixes"></a>

* Keycloak SAML components updated to 26.6.2 to address upstream advisories and maintain current support.
* **KSC-522** — SAML authentication bypass class vulnerability mitigated by enforcing signed SAML Response requirements and comprehensive assertion checks. The exploit path was validated, remediated, and regression-tested.

#### Compatibility & Upgrade Notes <a href="#compatibility-and-upgrade-notes" id="compatibility-and-upgrade-notes"></a>

* No admin-side configuration updates are required.
* We recommend validating SSO sign-in with your IdP (Okta, Entra ID, ADFS, Ping, Keycloak) in a non-production environment prior to production rollout.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/release-notes/enterprise/sso-connect/sso-connect-on-prem-17.0.2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
