+  "summary": "Parse Server's Cloud Hooks and Cloud Jobs bypass `readOnlyMasterKey` write restriction",
+  "details": "### Impact\n\nParse Server's `readOnlyMasterKey` option allows access with master-level read privileges but is documented to deny all write operations. However, some endpoints incorrectly accept the `readOnlyMasterKey` for mutating operations. This allows a caller who only holds the `readOnlyMasterKey` to create, modify, and delete Cloud Hooks and to start Cloud Jobs, which can be used for data exfiltration.\n\nAny Parse Server deployment that uses the `readOnlyMasterKey` option is affected. Note than an attacker needs to know the `readOnlyMasterKey` to exploit this vulnerability.\n\n### Patches\n\nThe fix adds authorization checks, rejecting mutating requests made with the `readOnlyMasterKey`.\n\n### Workarounds\n\nThere is no known workaround other than upgrading. If upgrading is not immediately possible, ensure the `readOnlyMasterKey` value is not shared with untrusted parties.\n\n### Resources\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-vc89-5g3r-cmhh\n- Fixed in Parse Server 9.4.1-alpha.3: https://github.com/parse-community/parse-server/releases/tag/9.4.1-alpha.3\n- Fixed in Parse Server 8.6.4: https://github.com/parse-community/parse-server/releases/tag/8.6.4",
