Technical details
A schema disclosure vulnerability exists in Parse Server's GraphQL API due to improper error handling during variable coercion. While the 'graphQLPublicIntrospection' setting (default: false) is intended to prevent schema discovery, the system still returns 'Did you mean...?' suggestions in error messages when a user provides near-miss enum values or input-object field names. This occurs because the existing introspection-hardening controls only applied to the validation phase, not the variable coercion phase. An unauthenticated remote attacker with only the public application ID can iteratively brute-force and recover hidden schema identifiers, including Cloud Code function names and Parse class/field names. This issue is a bypass of a previous fix (GHSA-8cph-rgr4-g5vj) and is resolved in versions 9.10.0-alpha.4 and 8.6.85.
