Authorization Bypass Through User-Controlled Key

Summary

Sentry is a developer-first error tracking and performance monitoring platform. An authenticated user can mute alert rules from arbitrary organizations and projects with a know rule ID. The user does not need to be a member of the organization or have permissions on the project. In our review, we have identified no instances where alerts have been muted by unauthorized parties. A patch was issued to ensure authorization checks are properly scoped on requests to mute alert rules. Authenticated users who do not have the necessary permissions are no longer able to mute alerts. Sentry SaaS users do not need to take any action. The rule mute feature was generally available as of 23.6.0 but users with early access may have had the feature as of 23.4.0. There are no known workarounds for this vulnerability. This issue affects sentry versions 23.4.0 through 24.8.0.
