{"id":"CVE-2026-30863","state":"PUBLISHED","title":"Parse Server: JWT audience validation bypass in Google, Apple, and Facebook authentication adapters","description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.10 and 9.5.0-alpha.11, the Google, Apple, and Facebook authentication adapters use JWT verification to validate identity tokens. When the adapter's audience configuration option is not set (clientId for Google/Apple, appIds for Facebook), JWT verification silently skips audience claim validation. This allows an attacker to use a validly signed JWT issued for a different application to authenticate as any user on the target Parse Server. This issue has been patched in versions 8.6.10 and 9.5.0-alpha.11.","publishedAt":"2026-03-07T16:18:47.786Z","updatedAt":"2026-03-09T18:25:24.090Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["parse-community parse-server"],"affected":[{"vendor":"parse-community","product":"parse-server","versions":[{"version":"< 8.6.10","status":"affected"},{"version":"< 9.5.0-alpha.11","status":"affected"}]}],"references":["https://github.com/parse-community/parse-server/security/advisories/GHSA-x6fw-778m-wr9v"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/30xxx/CVE-2026-30863.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-30863","state":"PUBLISHED","datePublished":"2026-03-07T16:18:47.786Z","dateUpdated":"2026-03-09T18:25:24.090Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-05T21:27:35.342Z"},"containers":{"cna":{"title":"Parse Server: JWT audience validation bypass in Google, Apple, and Facebook authentication adapters","descriptions":[{"lang":"en","value":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js.
