Project: SAML SSO - Service Provider  [1]
Date: 2026-September-09
Security risk: *Moderately critical* 11 ∕ 25
AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Server Side Request Forgery

Affected versions: <3.2.0
CVE IDs: CVE-2026-87953
Description: 
This module allows you to configure your Drupal site as a SAML 2.0 Service
Provider so that users can authenticate through an external identity
provider.

The module does not sufficiently validate URLs obtained from identity
provider metadata. An attacker with the ability to configure identity
provider metadata could cause the application to make requests to unintended
destinations, potentially allowing access to internal network resources.

This vulnerability is mitigated by the fact that an attacker must have
permission to configure identity provider metadata.

Solution: 
Install the latest version:

 * Upgrade to miniorange_saml 3.2.0 [3].
