drupal/miniorange_saml is vulnerable to Insufficient Replay Protection
48
Medium Risk
This Affects:
drupal/miniorange_samlTL;DR
The miniOrange SAML SSO Service Provider module lets a Drupal site authenticate users through an external SAML identity provider. Affected versions do not sufficiently prevent reuse of previously accepted SAML assertions. Under certain circumstances, a valid assertion may be replayed within its validity period, potentially allowing repeated authentication attempts using the same assertion. This vulnerability is mitigated by the fact that an attacker must first obtain a valid SAML assertion and can only reuse it during the assertion's validity period.

You are affected if you are using a version that falls within the vulnerable range.
