Sentry improperly authorizes deletion of user issue alert notifications
### Impact
An authenticated user may delete user issue alert notifications for arbitrary users given a known alert ID.
### Patches
A patch was issued to ensure authorization checks are properly scoped on requests to delete user alert notifications.
Sentry SaaS users do not need to take any action. Self-Hosted Sentry
https://github.com/getsentry/self-hosted users should upgrade to version **24.9.0** or higher.
