Fixed In Version: mquery 3.2.3
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in mquery that allows a prototype pollution attack. This flaw allows an attacker to alter the code behavior by modifying the object prototype. A flaw in the lib/utils.js function allows cloning and merging objects without sanitizing their special properties, such as prototype defining "__proto__". The highest threat from this vulnerability is to integrity.

Description Michael Kaplan 2021-02-16 17:10:07 UTC 
lib/utils.js in mquery before 3.2.3 allows a pollution attack because a special property (e.g., __proto__) can be copied during a merge or clone operation.

Comment 7 Jan Werner 2021-03-22 17:42:45 UTC 
Statement:

The affected version of mquery is a dependency of mongoose library. The exploitation of this vulnerability requires authenticated access, consequently the CVSSv3 score for RHACM is lower then the score of the flaw.
