What is CVE-2026-78336?

An issue has been identified in Apache Syncope that allows authenticated users to retrieve a list of configured OIDC providers for Single Sign-On (SSO).

It is crucial for users running affected versions to upgrade to 4.0.8 or 4.1.3 to mitigate this security risk.

Affected Version(s)

Apache Syncope 3.0.0-M0 <= 3.0.16

Apache Syncope 4.0.0-M0 <= 4.0.7

Apache Syncope 4.1.0-M0 <= 4.1.2
