Version Details and Security Vulnerabilities

Versions of lodash.merge before 4.6.1 are vulnerable to Prototype Pollution. The function 'merge' may allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.

Recommendation

Update to version 4.6.1 or later.

Versions of lodash.merge before 4.6.2 are vulnerable to prototype pollution. The function merge may allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.

Recommendation

Update to version 4.6.2 or later.

Versions of tunnel-agent before 0.6.0 are vulnerable to memory exposure.

This is exploitable if user supplied input is provided to the auth value and is a number.

Proof-of-concept:

require('request')({
  method: 'GET',
  uri: 'http://www.example.com',
  tunnel: true,
  proxy:{
    protocol: 'http:',
    host:'127.0.0.1',
    port:8080,
    auth:USERSUPPLIEDINPUT // number
  }
});

Recommendation

Update to version 0.6.0 or later.

The got package before 11.8.5 and 12.1.0 for Node.js allows a redirect to a UNIX socket.

Affected versions of string are vulnerable to regular expression denial of service when specifically crafted untrusted user input is passed into the underscore or unescapeHTML methods.

Recommendation

There is currently no direct patch for this vulnerability.

Currently, the best solution is to avoid passing user input to the underscore and unescapeHTML methods.

Alternatively, a user provided patch is available in Pull Request #217, however this patch has not been tested, nor has it been merged by the package author.
