BIT-parse-2026-30228 — Parse Server: File creation and deletion bypasses `readOnlyMasterKey` write restriction

Affected: Bitnami: parse

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, the readOnlyMasterKey can be used to create and delete files via the Files API (POST /files/:filename, DELETE /files/:filename). This bypasses the read-only restriction which violates the access scope of the readOnlyMasterKey. Any Parse Server deployment that uses readOnlyMasterKey and exposes the Files API is affected. An attacker with access to the readOnlyMasterKey can upload arbitrary files or delete existing files. This issue has been patched in versions 8.6.5 and 9.5.0.

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 read-only restriction which violates the access scope of the readOnlyMasterKey. Any Parse Server deployment that uses readOnlyMasterKey and exposes the Files API is affected. An attacker with access to the readOnlyMasterKey can upload arbitrary files or delete existing files. This issue has been patched in versions 8.6.5 and 9.5.0-alpha.3.

GHSA-xfh7-phr7-gr2x — parse-server's file creation and deletion bypasses `readOnlyMasterKey` write restriction

Affected: npm: parse-server

### Impact

The `readOnlyMasterKey` can be used to create and delete files via the Files API (`POST /files/:filename`, `DELETE /files/:filename`). This bypasses the read-only restriction which violates the access scope of the `readOnlyMasterKey`.

Any Parse Server deployment that uses `readOnlyMasterKey` and exposes the Files API is affected. An attacker with access to the `readOnlyMasterKey` can upload arbitrary files or delete existing files.

### Patches

The fix adds permission checks to both the file upload and file delete handlers.

### Workarounds

There is no workaround other than not using `readOnlyMasterKey`, or restricting network access to the Files API endpoints.
