{"id":"GHSA-7xg7-rqf6-pw6c","summary":"Parse Server: Classes `_GraphQLConfig` and `_Audience` master key bypass via generic class routes","details":"### Impact\n\nThe `_GraphQLConfig` and `_Audience` internal classes can be read, modified, and deleted via the generic `/classes/_GraphQLConfig` and `/classes/_Audience` REST API routes without master key authentication. This bypasses the master key enforcement that exists on the dedicated `/graphql-config` and `/push_audiences` endpoints. An attacker can read, modify and delete GraphQL configuration and push audience data.\n\n### Patches\n\nThe fix adds the affected internal classes to the `classesWithMasterOnlyAccess` list, ensuring that the generic `/classes/` routes enforce master key access consistently with the dedicated endpoints.\n\n### Workarounds\n\nThere is no known workaround.\n\n### References\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-7xg7-rqf6-pw6c\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.12\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.25","aliases":["BIT-parse-2026-31800","CVE-2026-31800"],"modified":"2026-03-14T03:41:17.892207Z","published":"2026-03-11T00:23:01Z","database_specific":{"cwe_ids":["CWE-862"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-11T00:23:01Z","nvd_published_at":"2026-03-10T21:16:49Z"},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-7xg7-rqf6-pw6c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31800"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/8.6.25"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/9.5.2-alpha.12"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0-alpha.1"},{"fixed":"9.5.2-alpha.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-7xg7-rqf6-pw6c/GHSA-7xg7-rqf6-pw6c.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.25"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-7xg7-rqf6-pw6c/GHSA-7xg7-rqf6-pw6c.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
