CVE-2026-47248: CWE-209: Generation of Error Message Containing Sensitive Information in parse-community parse-server
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.78 and 9.9.1-alpha.2, Parse Server's GraphQL endpoint discloses schema metadata to unauthenticated callers through Did you mean ...? suggestions embedded in GraphQL validation-error messages. An unauthenticated caller who knows only the public application id can iteratively send malformed queries to reconstruct class names, field names, argument names, mutation names, and input-object fields. This issue has been patched in versions 8.6.78 and 9.9.1-alpha.2.

Technical Summary
CVE-2026-47248 affects parse-community's parse-server by leaking schema metadata through GraphQL validation error messages. Unauthenticated attackers can exploit the 'Did you mean ...?' suggestions in error responses to enumerate internal schema elements like class names, field names, argument names, mutation names, and input-object fields. This information disclosure vulnerability is due to error messages containing sensitive information (CWE-209). The vulnerability is fixed in parse-server versions 8.6.78 and 9.9.1-alpha.2.
Potential Impact
An unauthenticated attacker who knows only the public application ID can gather detailed schema information by sending malformed GraphQL queries. This information disclosure can aid attackers in crafting more targeted attacks against the backend by revealing internal structure and naming conventions. There is no indication of privilege escalation or direct data compromise from this vulnerability alone.
Mitigation Recommendations
This vulnerability has been patched in parse-server versions 8.6.78 and 9.9.1-alpha.2. Users should upgrade to at least version 8.6.78 or later to remediate this issue. No additional mitigations are specified or required once patched.
