CVE-2026-121414
Published:November 03, 2026
Updated:November 04, 2026
Parse Server before 8.6.110 and 9.0.0 before 9.10.6-alpha.2 fails to contain a serialization error when an object update uses a dot notation key targeting a pointer field's object identifier on a class with an afterSave trigger. Attackers, including unauthenticated clients when objects are writable without a session, can send such an update to crash the Node process.
