Parse Server

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.

Parse Server before 8.6.95 and 9.0.0 before 9.10.2-alpha.3 does not resolve file references lacking a URL before passing objects to Cloud Code triggers and LiveQuery, causing an uncaught exception that terminates the process. Attackers able to write to a class with Cloud Code save, find, or delete triggers or LiveQuery enabled, including unauthenticated users when public write access or sign-up is allowed, can crash the server or break subsequent requests.

Parse Server 8.2.2 before 8.6.94 and 9.0.0 before 9.10.1-alpha.14 applies its GraphQL introspection control only to operation text sent directly with a request, not to operations resolved from Apollo Server's automatic persisted query cache. Unauthenticated attackers holding the public Application Id and client key can replay an introspection query previously cached by a master or maintenance key client to retrieve the schema, including private class and field names.

Parse Server from 9.7.0 before 9.10.5-alpha.7 contains an information disclosure vulnerability that allows clients to receive protected field values written by beforeSave triggers using dot notation keys. When protectedFieldsSaveResponseExempt is set to false, clients with create or update permission can read values a trigger writes beneath a protected field in the same request.

Parse Server from 9.7.0 before 9.10.5-alpha.10 contains an authorization flaw that applies _Installation updates addressed by object ID to the installation named in the X-Parse-Installation-Id header. When protectedFieldsTriggerExempt is enabled, attackers knowing another installation's object ID can make a beforeSave trigger process that installation's protected fields while writing elsewhere.
