  • GHSA-f825-f98c-gj3gautomattic/mongoose vulnerable to Prototype pollution via Schema.path2022-07-29ghsa · osvUS

    Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Affected versions of this package are vulnerable to Prototype Pollution. The `Schema.path()` function is vulnerable to prototype pollution when setting the schema object. This vulnerability allows modification of the Object prototype and could be manipulated into a Denial of Service (DoS) attack.
