Aliases CVE-2026-29182
GHSA-vc89-5g3r-cmhh
Summary Parse Server's Cloud Hooks and Cloud Jobs bypass `readOnlyMasterKey` write restriction Parse 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. Any Parse Server deployment that uses the `readOnlyMasterKey` option is affected. Note than an attacker needs to know the `readOnlyMasterKey` to exploit this vulnerability.
