Parse Dashboard is a standalone dashboard for managing Parse Server apps. In versions 7.3.0-alpha.42 through 9.0.0-alpha.7, the "ConfigKeyCache" uses the same cache key for both master key and read-only master key when resolving function-typed keys. Under specific timing conditions, a read-only user can receive the cached full master key, or a regular user can receive the cached read-only master key. The fix in version 9.0.0-alpha.8 uses distinct cache keys for master key and read-only master key. As a workaround, avoid using function-typed master keys, or remove the "agent" configuration block from your dashboard configuration.
