In Sentry 25.1.0 through 25.5.1, an authenticated attacker can access a project's issue endpoint and perform unauthorized actions (such as adding a comment) without being a member of the project's team. A seven-digit issue ID must be known (it is not treated as a secret and might be mentioned publicly, or it could be predicted).
