{"cve":"CVE-2023-36829","nvd":{"published":"2023-07-06T23:15:09.620","modified":"2026-06-17T06:07:10.037","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-697","CWE-863","CWE-942"],"references":["https://github.com/getsentry/self-hosted/releases/tag/23.6.2","https://github.com/getsentry/sentry/commit/ee44c6be35e5e464bc40637580f39867898acd8b","https://github.com/getsentry/sentry/pull/52276","https://github.com/getsentry/sentry/security/advisories/GHSA-4xqm-4p72-87h6","https://github.com/getsentry/self-hosted/releases/tag/23.6.2"],"products":["functional:sentry"],"source":"nvd","synced_at":"2026-10-19T21:38:30.124994567+00:00"},"epss":{"cve":"CVE-2023-36829","score":0.00666,"percentile":0.51832,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4xqm-4p72-87h6","url":"https://osv.dev/vulnerability/GHSA-4xqm-4p72-87h6","summary":"Sentry CORS misconfiguration","modified":"2026-09-10T03:50:08.444402599Z","packages":[{"ecosystem":"PyPI","name":"sentry","purl":"pkg:pypi/sentry","ranges":[">=23.6.0 <23.6.2"],"fixed":["23.6.2"]}]},{"id":"PYSEC-2023-115","url":"https://osv.dev/vulnerability/PYSEC-2023-115","summary":"","modified":"2023-11-08T04:12:59.617813Z","packages":[{"ecosystem":"PyPI","name":"sentry","purl":"pkg:pypi/sentry","ranges":[">=23.6.0 <23.6.2"],"fixed":["23.6.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
