Send is a Node.js package designed for efficient streaming of static files, equipped with essential features like Range support for partial content delivery and conditional-GET handling for optimized caching. Comparing versions 0.15.3 and 0.15.2 reveals subtle yet significant updates. Both versions share the same core functionality, offering developers a robust solution for serving static assets. Key features remain consistent including the utilization of packages like etag for generating HTTP ETags, range-parser for handling Range requests, and fresh for determining cache freshness.
The primary difference lies in the dependency updates. Version 0.15.3 upgrades the ms dependency from "1.0.0" to "2.0.0" and debug from "2.6.4" to "2.6.7". While seemingly minor, such dependency updates often include bug fixes, performance improvements, and security enhancements within those respective modules. Additionally, eslint-plugin-markdown was updated from "1.0.0-beta.4" to "1.0.0-beta.6". Developers should evaluate these changes to ensure compatibility and leverage any potential benefits.
Choosing between these versions necessitates considering the specific needs of your project. If utilizing the latest features and refinements within ms and debug is crucial, upgrading to 0.15.3 is advisable. Otherwise, version 0.15.2 may suffice, particularly if maintaining dependency stability is a priority. Both offer a reliable static file serving solution, empowering developers to deliver content efficiently.
All the vulnerabilities related to the version 0.15.3 of the package
send vulnerable to template injection that can lead to XSS
passing untrusted user input - even after sanitizing it - to SendStream.redirect() may execute untrusted code
this issue is patched in send 0.19.0
users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist
successful exploitation of this vector requires the following:
mime Regular Expression Denial of Service when MIME lookup performed on untrusted user input
Affected versions of mime are vulnerable to regular expression denial of service when a mime lookup is performed on untrusted user input.
Update to version 2.0.3 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 fresh
Affected versions of fresh are vulnerable to regular expression denial of service when parsing specially crafted user input.
Update to version 0.5.2 or later.
