Improper Input Validation in Automattic Mongoose

Source: GitHub Advisory Database (reviewed) Critical CVE-2019-17426

Packages

Ecosystem	Package	Affected	Fixed in
npm	mongoose	>= 5.0.0, < 5.7.5	5.7.5
npm	mongoose	< 4.13.21	4.13.21

Details

As written in the advisory (Markdown source, shown as plain text).

Automattic Mongoose through 5.7.4 allows attackers to bypass access control (in some applications) because any query object with a `_bsontype` attribute is ignored. For example, adding `"_bsontype":"a"` can sometimes interfere with a query filter. NOTE: this CVE is about Mongoose's failure to work around this _bsontype special case that exists in older versions of the bson parser (aka the mongodb/js-bson project).
