  • 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-2020-7774 EPSS 70%

    Prototype Pollution

    The package y18n before 3.2.2, 4.0.1 and 5.0.5, is vulnerable to Prototype Pollution.

  • 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.
