CVE-2026-109954— Parse Server 9.0.0 before 9.10.2-alpha.5 Transactional Batch Request Write Interference

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.

在 Parse Server 5.4.0 至 8.6.96（不含 8.6.96）以及 9.0.0 至 9.10.2-alpha.5（不含 9.10.2-alpha.5）版本中，事务性批量操作的状态在并发请求之间被共享，导致任何客户端的事务性批量请求都可能干扰其他客户端的数据库写入操作。在 PostgreSQL 或 MongoDB 副本集及分片集群环境下，若批量操作失败，其他客户端已确认的写入操作将被回滚；同时，PostgreSQL 事务可能无限期保持开启状态，从而导致后续的写入操作失败。

Vulnerability Title
Parse Server 9.0.0 before 9.10.2-alpha.5 Transactional Batch Request Write Interference
Source: CVE Program / CVE List V5
Vulnerability Description
Parse Server 5.4.0 before 8.6.96 and 9.0.0 before 9.10.2-alpha.5 shares transactional batch state across concurrent requests, letting any client's transactional batch request interfere with other clients' database writes. On PostgreSQL or MongoDB replica sets and sharded clusters, other clients' acknowledged writes are rolled back if the batch fails, and PostgreSQL transactions can remain open indefinitely, causing subsequent writes to fail.
