{"id":"CVE-2026-30863","aliases":["BIT-parse-2026-30863","GHSA-x6fw-778m-wr9v"],"url":"https://o3.security/vulnerability/CVE-2026-30863","summary":"Parse Server: JWT audience validation bypass in Google, Apple, and Facebook authentication adapters","details":"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.","published":"2026-03-07T16:18:47.786Z","modified":"2026-08-07T11:31:16.186979145Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.5.0-alpha.11"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.10"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30863.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-x6fw-778m-wr9v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30863"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:16.186979145Z"}}
