Send is a Node.js package designed for efficiently serving static files with advanced features like Range and conditional-GET support, optimizing bandwidth usage and improving user experience. The jump from version 0.13.1 to 0.13.2 introduces subtle but notable changes for developers. Both versions share the same core functionality and dependencies, including essential modules like ms for time conversion, depd for deprecated feature warnings, etag for generating entity tags, mime for content-type detection, and debug for logging, ensuring consistent performance in handling various file types and network conditions.
A primary difference lies in the development dependencies, specifically the version of mocha, a popular JavaScript testing framework. Version 0.13.1 uses mocha 2.3.4, while 0.13.2 upgrades to 2.4.5. This suggests potential improvements in the testing suite, possibly including enhanced test coverage or bug fixes within the testing framework itself. While this change doesn't directly impact the library's runtime behavior, it signals a commitment to maintaining code quality and stability.
Furthermore, the release dates indicate a roughly two-month gap between the versions, with 0.13.2 being released in March 2016 and 0.13.1 in January 2016. This timeframe implies that version 0.13.2 likely incorporates bug fixes, performance enhancements, or minor feature tweaks identified since the previous release, making it the preferred choice for projects seeking the most up-to-date and refined version of the send package. Choosing the latest version grants access to the most current improvements and ensures better compatibility with modern Node.js environments.
All the vulnerabilities related to the version 0.13.2 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:
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.
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.
