描述

### 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. ### References - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-xfh7-phr7-gr2x - Fix for Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.5.0-alpha.3 - Fix for Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.5
