Affected packages

• PyPI sentry: >= 23.6.0, < 23.6.2 → fixed in 23.6.2

Description

Impact 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. Patches The patch has been released in Sentry 23.6.2. Workarounds For Sentry SaaS customers, no action is needed. 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. There are no known workarounds.
