{"id":"PYSEC-2023-115","details":"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.","aliases":["CVE-2023-36829","GHSA-4xqm-4p72-87h6"],"modified":"2023-11-08T04:12:59.617813Z","published":"2023-07-06T23:15:00Z","references":[{"type":"FIX","url":"https://github.com/getsentry/sentry/commit/ee44c6be35e5e464bc40637580f39867898acd8b"},{"type":"FIX","url":"https://github.com/getsentry/sentry/security/advisories/GHSA-4xqm-4p72-87h6"},{"type":"FIX","url":"https://github.com/getsentry/sentry/pull/52276"},{"type":"WEB","url":"https://github.com/getsentry/self-hosted/releases/tag/23.6.2"}],"affected":[{"package":{"name":"sentry","ecosystem":"PyPI","purl":"pkg:pypi/sentry"},"ranges":[{"type":"GIT","repo":"https://github.com/getsentry/sentry","events":[{"introduced":"0"},{"fixed":"ee44c6be35e5e464bc40637580f39867898acd8b"}]},{"type":"ECOSYSTEM","events":[{"introduced":"23.6.0"},{"fixed":"23.6.2"}]}],"versions":["23.6.0","23.6.1"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/sentry/PYSEC-2023-115.yaml"}}],"schema_version":"1.7.3"}
