CVE-2026-105828— Parse Server 9.0.0 before 9.10.1-alpha.12 Class Name Disclosure via GraphQL Errors

Quick assessment

Affected
parse-community parse-server
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Parse Server 8.2.2 至 8.6.92（不含 8.6.92）以及 9.0.0 至 9.10.1-alpha.12（不含 9.10.1-alpha.12）存在一个信息泄露漏洞。当禁用公开的内省（introspection）功能时，GraphQL 验证错误消息会泄露隐藏的类名。未经身份验证的攻击者仅需拥有公开的 Application Id，即可发送精心构造的操作，触发“未知参数”或“无效枚举值”等错误，从而获取指针（pointer）和关系（relation）目标类的信息。
