CVE-2023-36829 Information

Description

Sentry is an error tracking and performance monitoring platform. Starting in version 23.6.0 and prior to version 23.6.2 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. The patch has been released in Sentry 23.6.2.
