CVE-2026-34363— Parse Server 竞争条件问题漏洞

Parse Server: LiveQuery protected field leak via shared mutable state across concurrent subscribers

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.65 and 9.7.0-alpha.9, when multiple clients subscribe to the same class via LiveQuery, the event handlers process each subscriber concurrently using shared mutable objects. The sensitive data filter modifies these shared objects in-place, so when one subscriber's filter removes a protected field, subsequent subscribers may receive the already-filtered object. This can cause protected fields and authentication data to leak to clients that should not see them, or cause clients that should see the data to receive an incomplete object. Additionally, when an afterEvent Cloud Code trigger is registered, one subscriber's trigger modifications can leak to other subscribers through the same shared mutable state. Any Parse Server deployment using LiveQuery with protected fields or afterEvent triggers is affected when multiple clients subscribe to the same class. This issue has been patched in versions 8.6.65 and 9.7.0-alpha.9.

Parse Server 竞争条件问题漏洞

Parse Server是Parse Platform开源的一个开源后端，可以部署到任何可以运行 Node.js 的基础设施。 Parse Server 8.6.65之前版本和9.7.0-alpha.9之前版本存在竞争条件问题漏洞，该漏洞源于敏感数据过滤器对共享可变对象进行就地修改，可能导致受保护字段和身份验证数据泄露。
