{"id":"CVE-2026-31800","aliases":["BIT-parse-2026-31800","GHSA-7xg7-rqf6-pw6c"],"url":"https://o3.security/vulnerability/CVE-2026-31800","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","published":"2026-03-10T20:51:14.338Z","modified":"2026-08-12T03:51:35.641706557Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.5.2-alpha.12"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.25"}],"fix":null,"references":[{"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"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31800.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.641706557Z"}}
