Parse Server is an open source http web server backend. In versions prior to 4.10.7 there is a Remote Code Execution (RCE) vulnerability in Parse Server. This vulnerability affects Parse Server in the default configuration with MongoDB. The main weakness that leads to RCE is the Prototype Pollution vulnerable code in the file `DatabaseController.js`, so it is likely to affect Postgres and any other database backend as well. This vulnerability has been confirmed on Linux (Ubuntu) and Windows. Users are advised to upgrade as soon as possible. The only known workaround is to manually patch your installation with code referenced at the source GHSA-p6h4-93qp-jhcm.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
