Summary
Parse Server has denylist `requestKeywordDenylist` keyword scan bypass through nested object placement
Details

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.12 and 9.5.1-alpha.1, the requestKeywordDenylist security control can be bypassed by placing any nested object or array before a prohibited keyword in the request payload. This is caused by a logic bug that stops scanning sibling keys after encountering the first nested value. Any custom requestKeywordDenylist entries configured by the developer are equally by-passable using the same technique. All Parse Server deployments are affected. The requestKeywordDenylist is enabled by default. This vulnerability is fixed in 8.6.12 and 9.5.1-alpha.1. Use a Cloud Code beforeSave trigger to validate incoming data for prohibited keywords across all classes.
