    CVE-2019-10746

    Prototype Pollution in mixin-deep

    mixin-deep is vulnerable to Prototype Pollution in versions before 1.3.2 and version 2.0.0. The function mixin-deep could be tricked into adding or modifying properties of Object.prototype using a constructor payload.

  • Critical 9.8
    CVE-2019-10747

    Prototype Pollution in set-value

    set-value is vulnerable to Prototype Pollution in versions lower than 3.0.1. The function mixin-deep could be tricked into adding or modifying properties of Object.prototype using any of the constructor, prototype and _proto_ payloads.

  • High 7.5
    CVE-2020-7754

    Regular Expression Denial of Service (ReDoS)

    This affects the package npm-user-validate before 1.0.1. The regex that validates user emails took exponentially longer to process long input strings beginning with @ characters.

  • High 7.3
    CVE-2020-7788

    Prototype Pollution

    This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.
