## Summary

The alerting contact point feature of this software is affected. A user who can edit contact points, but not their protected fields, can change protected settings such as the destination URL by switching an integration to an older schema, which can expose stored credentials and redirect alert notifications.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Grafana Grafana Enterprise: from 12.4.0, through 12.4.13; from 13.0.0, through 13.0.11; from 13.1.0, through 13.1.8; from 13.2.0, through 13.2.4
- Grafana Grafana OSS: from 12.4.0, through 12.4.13; from 13.0.0, through 13.0.11; from 13.1.0, through 13.1.8; from 13.2.0, through 13.2.4

## Description

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).
