Document deletion and process crash via unvalidated method-name dispatch in atomic pop operation

Mongoid contains an unsafe reflection weakness in the document persistence layer of its object-document mapping code. Input whose keys are passed through from an unauthenticated party by an embedding application can cause unintended internal method invocation instead of the intended array field...

Cross-principal document update, theft, and deletion via unvalidated id in nested attributes

An insecure direct object reference in the nested attributes handling of the Mongoid object-document mapper may allow a user with basic application privileges to reference a record identifier that is not their own. Processing such a request can cause that record to be looked up without the usual...

Integer Underflow → Heap Out-of-Bounds Read in `bson_new_from_buffer()

A missing lower-bound validation in the bsonnewfrombuffer function of libbson allows an integer underflow when processing BSON data with a zero-length prefix. The function reads a 32-bit document length from the input buffer but does not verify that the value is at least 5 the minimum valid BSON...
