CVE-2026-47248 parse-community CVE debrief

CVE-2026-47248 is a vulnerability in Parse Server, an open-source backend that can be deployed to any infrastructure running Node.js. The vulnerability affects the GraphQL endpoint, which discloses schema metadata to unauthenticated callers through 'Did you mean ...?' suggestions embedded in GraphQL validation-error messages. This allows an unauthenticated caller with only the public application ID to iteratively send malformed queries to reconstruct class names, field names, argument names, mutation names, and input-object fields. The issue has been patched in versions 8.6.78 and 9.9.1-alpha.2.
