Overview
@payloadcms/db-mongodb is a The officially supported MongoDB database adapter for Payload
Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the beforeValidate hook's array and blocks field processing, when null or non-object values are present in array or blocks field rows. An authenticated attacker can submit a document payload containing null entries in array or blocks fields, bypassing downstream validation logic that expects plain objects - for example, property assignment such as row.blockType = ... - which can corrupt document data and allow unintended writes to the database.
