Parse Server from 9.7.0 before 9.10.5-alpha.10 contains an authorization flaw that applies _Installation updates addressed by object ID to the installation named in the X-Parse-Installation-Id header. When protectedFieldsTriggerExempt is enabled, attackers knowing another installation's object ID can make a beforeSave trigger process that installation's protected fields while writing elsewhere.
