Serve-index is a valuable Node.js middleware for Express applications, enabling automatic directory listings, enhancing the development experience and facilitating file sharing. Comparing version 1.5.3 with its predecessor, 1.5.2, reveals incremental improvements focusing on dependency updates.
Specifically, version 1.5.3 updates accepts from ~1.1.3 to ~1.1.4, mime-types from ~2.0.3 to ~2.0.4, and http-errors from ~1.2.7 to ~1.2.8. These updates likely include bug fixes, performance tweaks, and security enhancements within those respective dependencies. Additionally, istanbul was updated from 0.3.3 to 0.3.5.
For developers using serve-index, these changes imply a more reliable and potentially faster experience. While the core functionality of serving directory listings remains consistent, leveraging the latest dependencies ensures compatibility and takes advantage of the improvements made by the wider Node.js ecosystem. The updates to mime-types would suggest further improvements to file extentions definitions. Consequently, upgrading to version 1.5.3 is recommended for projects already using serve-index, as it offers a refined middleware solution. Staying updated with revisions such as these ensures the ongoing operation and stability of your software.
All the vulnerabilities related to the version 1.5.3 of the package
Cross-Site Scripting in serve-index
Versions 1.6.2 and earlier of serve-index are affected by a cross-site scripting vulnerability. Because file and directory names are not escaped in the module's HTML output, a remote attacker that can influence file or directory names can launch a persistent cross-site scripting attack on the application.
Update to version 1.6.3 or later.
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.
Regular Expression Denial of Service in negotiator
Affected versions of negotiator are vulnerable to regular expression denial of service attacks, which trigger upon parsing a specially crafted Accept-Language header value.
Update to version 0.6.1 or later.
