# CVE-2026-100105: Alerting contact point authorization bypass via schema downgrade

Status: published. Published: 2026-10-28. Updated: 2026-11-05.

A user with permission to edit contact points but not their protected fields can change protected settings, such as a contact point's destination URL, by switching an integration to a legacy schema version, which can expose stored credentials and redirect alert notifications (incorrect authorization).
