CVE-2019-17426
Improper Input Validation in Automattic Mongoose
9.1
CRITICAL
CVSS 3.1
EPSS 0.24%
Description
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).
