{"id":"GHSA-q3p6-g7c4-829c","summary":"GraphQL API endpoint ignores CORS origin restriction","details":"### Impact\n\nThe GraphQL API endpoint does not respect the `allowOrigin` server option and unconditionally allows cross-origin requests from any website. This bypasses origin restrictions that operators configure to control which websites can interact with the Parse Server API. The REST API correctly enforces the configured `allowOrigin` restriction.\n\n### Patches\n\nThe GraphQL API endpoint now uses the same CORS middleware as the REST API, ensuring the `allowOrigin` and `allowHeaders` server options are consistently enforced across all endpoints.\n\n### Workarounds\n\nThere is no known workaround other than upgrading.\n\n### Resources\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-q3p6-g7c4-829c\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/pull/10334\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/pull/10335","aliases":["BIT-parse-2026-34373","CVE-2026-34373"],"modified":"2026-04-06T15:27:10.053932311Z","published":"2026-03-30T18:05:47Z","database_specific":{"github_reviewed_at":"2026-03-30T18:05:47Z","nvd_published_at":"2026-03-31T15:16:19Z","cwe_ids":["CWE-346"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-q3p6-g7c4-829c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34373"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10334"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10335"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/0347641507891d0013ec57f7c10f012064f41263"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/4dd0d3d8be1c39664c74ad10bb0abaa76bc41203"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.7.0-alpha.10"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-q3p6-g7c4-829c/GHSA-q3p6-g7c4-829c.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.5.0"},{"fixed":"8.6.66"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-q3p6-g7c4-829c/GHSA-q3p6-g7c4-829c.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N"}]}
