{"id":"CVE-2023-36829","summary":"Sentry CORS misconfiguration vulnerability","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":["GHSA-4xqm-4p72-87h6","PYSEC-2023-115"],"modified":"2026-04-10T05:00:22.962762Z","published":"2023-07-06T22:08:58.922Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36829.json","cwe_ids":["CWE-863","CWE-942"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/getsentry/self-hosted/releases/tag/23.6.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36829.json"},{"type":"ADVISORY","url":"https://github.com/getsentry/sentry/security/advisories/GHSA-4xqm-4p72-87h6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-36829"},{"type":"FIX","url":"https://github.com/getsentry/sentry/commit/ee44c6be35e5e464bc40637580f39867898acd8b"},{"type":"FIX","url":"https://github.com/getsentry/sentry/pull/52276"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getsentry/self-hosted","events":[{"introduced":"dbded584377d50a2545a98de5d0d53d204b369a0"},{"fixed":"5c5bf06fae3ac6b8c60b4770d4ac985ea670103f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-36829.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/getsentry/sentry","events":[{"introduced":"0"},{"fixed":"ee44c6be35e5e464bc40637580f39867898acd8b"}]}],"versions":["1.10.0","1.10.1","1.11.0","1.11.1","1.11.2","1.11.3","1.4.3","1.6.2","1.6.4","1.6.5","1.6.7","1.6.8","1.6.8.1","1.7.3","1.8.8","2.0.0","2.0.0-RC5","2.0.0-RC7","2.0.0-RC9","2.0.1","2.0.2","2.1.0","2.1.1","2.1.2","2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.3.0","2.3.1","2.3.2","2.4.0","2.4.1","2.4.2","2.4.3","2.4.4","2.4.5","2.5.0","2.5.1","2.5.2","2.6.0","2.6.1","2.6.2","2.7.0","2.8.0","2.8.1","2.9.0","3.0.0","3.0.1","3.0.2","3.0.3","3.0.4","3.1.0","3.1.1","3.1.2","3.1.3","3.1.4","3.2.0","3.3.0","3.3.1","3.3.2","3.4.0","3.4.1","3.4.2","3.5.0","3.5.1","3.5.2","3.5.3","3.5.5","3.5.6","3.5.7","3.5.8","3.5.9","3.6.0","3.6.1","3.6.2","3.6.3","3.6.4","3.7.0","3.7.1","3.7.2","3.7.3","3.7.4","3.8.0","3.8.1","4.0.0","4.0.10","4.0.11","4.0.12","4.0.13","4.0.14","4.0.15","4.0.16","4.0.17","4.0.2","4.0.3","4.0.4","4.0.5","4.0.6","4.0.7","4.0.8","4.0.9","4.1.0","4.1.1","4.1.2","4.1.3","4.1.4","4.1.5","4.1.6","4.1.7","4.10.0","4.2.0","4.2.1","4.2.2","4.2.4","4.2.5","4.3.0","4.3.1","4.3.2","4.3.3","4.4.0","4.4.1","4.4.2","4.4.3","4.4.4","4.4.5","4.4.6","4.5.0","4.5.1","4.5.2","4.5.3","4.5.4","4.5.5","4.5.6","4.5.7","4.6.0","4.7.0","4.7.1","4.7.2","4.7.3","4.7.4","4.7.7","4.8.0","4.8.1","4.8.2","4.8.3","4.8.4","4.8.5","4.8.6","4.9.0","4.9.4","4.9.5","4.9.6","4.9.7","4.9.7.1","4.9.8","5.1.0","5.1.1","5.1.1.1","5.1.1.2","5.1.2","5.1.3","5.1.4","5.1.5","5.2.0","5.2.1","5.3.0","5.3.1","5.3.2","5.3.3","6.0.0","6.0.1","6.0.2","6.0.3","6.0.4","6.0.5","6.0.6","6.1.0","6.1.1","6.1.2","6.2.0","6.2.1","6.2.2","6.2.3","8.0.0","8.0.0-rc1","8.1.0","v1.10.0","v1.10.1","v1.11.0","v1.11.1","v1.11.2","v1.11.3","v1.6.2","v1.6.4","v1.6.5","v1.6.7","v1.6.8","v1.6.8.1","v1.7.3","v1.8.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-36829.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
