Jsftp is a Node.js library designed to provide a clean and reliable FTP client implementation for developers seeking to integrate FTP functionality into their applications. Versions 1.4.1 and 1.5.0 share a common foundation, offering a robust set of features for interacting with FTP servers. Both versions rely on the same core dependencies, including debug for enhanced logging, event-stream for data processing, ftp-response-parser for interpreting server responses, once for managing event emissions, and parse-listing for directory listing parsing. Development dependencies also remain consistent, employing tools such as mocha for testing, istanbul for code coverage, mocha-istanbul for integrating coverage reports, sinon for creating test spies and stubs, ftp-test-server for simulating FTP environments, and rimraf for file system cleanup.
The key difference between these versions lies in their release date, with version 1.5.0 being released on February 7, 2015, subsequent to version 1.4.1, released on January 27, 2015. While the core functionalities and dependencies appear identical, version 1.5.0 likely incorporates bug fixes, performance improvements, or minor enhancements that are not explicitly outlined in the provided metadata. Developers upgrading from 1.4.1 to 1.5.0 can expect a potentially more stable and refined experience, benefiting from any subtle improvements made by the maintainers. To use this library import or require the package and refer to the documentation. Ensure you handle potential errors during FTP operations elegantly.
All the vulnerabilities related to the version 1.5.0 of the package
debug Inefficient Regular Expression Complexity vulnerability
A vulnerability classified as problematic has been found in debug-js debug up to 3.0.x. This affects the function useColors of the file src/node.js. The manipulation of the argument str leads to inefficient regular expression complexity. Upgrading to version 3.1.0 is able to address this issue. The name of the patch is c38a0166c266a679c8de012d4eaccec3f944e685. It is recommended to upgrade the affected component. The identifier VDB-217665 was assigned to this vulnerability. The patch has been backported to the 2.6.x branch in version 2.6.9.
Regular Expression Denial of Service in debug
Affected versions of debug are vulnerable to regular expression denial of service when untrusted user input is passed into the o formatter.
As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.
This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1.
Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
Regular Expression Denial of Service in ms
Versions of ms prior to 0.7.1 are affected by a regular expression denial of service vulnerability when extremely long version strings are parsed.
var ms = require('ms');
var genstr = function (len, chr) {
var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
ms(genstr(process.argv[2], "5") + " minutea");
Showing increase in execution time based on the input string.

Vercel ms Inefficient Regular Expression Complexity vulnerability
A vulnerability, which was classified as problematic, has been found in vercel ms up to 1.x. This issue affects the function parse of the file index.js. The manipulation of the argument str leads to inefficient regular expression complexity. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.0.0 is able to address this issue. The name of the patch is caae2988ba2a37765d055c4eee63d383320ee662. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-217451.
