CVE-2026-87944 · Severity: info · Published 2026-10-22

The SAML SSO - Service Provider module for Drupal allows websites to authenticate users through external identity providers. The module fails to properly validate TLS certificates when communicating with these external services, allowing an attacker who intercepts network traffic to impersonate the identity provider and influence authentication communications. Successful exploitation could lead to unauthorized user account creation, session hijacking, or account takeover.
