CVE-2026-30229 Parse Server: Endpoint `/loginAs` allows `readOnlyMasterKey` to gain full read and write access as any user

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.6 and 9.5.0-alpha.4, the readOnlyMasterKey can call POST /loginAs to obtain a valid session token for any user. This allows a read-only credential to impersonate arbitrary...

CVE-2026-30228 Parse Server: File creation and deletion bypasses `readOnlyMasterKey` write restriction

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.5 and 9.5.0-alpha.3, the readOnlyMasterKey can be used to create and delete files via the Files API POST /files/:filename, DELETE /files/:filename. This bypasses the...

CVE-2026-30228

Parse Server is affected where the readOnlyMasterKey is used with the Files API (POST /files/:filename, DELETE /files/:filename). Prior to versions 8.6.5 and 9.5.0-alpha.3, this could bypass the read-only restriction, allowing an attacker with the readOnlyMasterKey to upload arbitrary files or de...
