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.","published_at":"2023-07-06T22:08:58.922000Z","last_modified_at":null,"cvss_v3_score":6.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-942","CWE-863"],"nvd_references":["https://github.com/getsentry/sentry/security/advisories/GHSA-4xqm-4p72-87h6","https://github.com/getsentry/sentry/pull/52276","https://github.com/getsentry/sentry/commit/ee44c6be35e5e464bc40637580f39867898acd8b","https://github.com/getsentry/self-hosted/releases/tag/23.6.2"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:33:40.240625Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"getsentry","vendor_name":"getsentry","product_slug":"sentry","product_name":"sentry","version_start":">= 23.6.0, < 23.6.2","version_start_inclusive":true,"version_end":">= 23.6.0, < 23.6.2","version_end_inclusive":true,"cpe23_uri":"cve5:getsentry:sentry:>= 23.6.0, < 23.6.2:>= 23.6.0, < 23.6.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/getsentry/sentry/security/advisories/GHSA-4xqm-4p72-87h6","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/getsentry/sentry/pull/52276","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/getsentry/sentry/commit/ee44c6be35e5e464bc40637580f39867898acd8b","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/getsentry/self-hosted/releases/tag/23.6.2","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2023-07-06T22:08:58.922000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:29:09.228203Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:09.228203Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:09.228203Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:33:40.240625Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:33:40.240625Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:33:40.240625Z","label":"SSVC decision revised","source":"vulnrichment"}]}
