Name of the Vulnerable Software and Affected Versions Sentry versions 23.6.0 through 23.6.1

Description Sentry is an error tracking and performance monitoring platform. The Sentry API incorrectly returns the access-control-allow-credentials: true HTTP header if the Origin request header ends with the system.base-hostname option of Sentry installation. This only affects installations that have system.base-hostname option explicitly set, as it is empty by default. Impact is limited since recent versions of major browsers have cross-site cookie blocking enabled by default. However, this flaw could allow other multi-step attacks.

Recommendations For self-hosted Sentry installations that have system.base-hostname explicitly set, it is recommended to upgrade the installation to 23.6.2 or higher. For Sentry SaaS customers, no action is needed.
