Send is a Node.js module designed for efficient streaming of static files, equipped with features like Range and conditional-GET support to optimize file delivery. Examining versions 0.13.1 and 0.13.0 reveals subtle yet important differences for developers.
Version 0.13.1, released in January 2016, includes updated dependencies, notably depd to version ~1.1.0, escape-html to ~1.0.3, and range-parser to ~1.0.3. Additionally, the internal package destroy has been updated to version ~1.0.4. This indicates potential bug fixes, security enhancements, or performance improvements within these underlying modules. The newer version also incorporates updated development dependencies such as mocha at version 2.3.4, istanbul at version 0.4.2, and supertest at 1.1.0, signifying advancements in testing and code coverage tools.
In contrast, version 0.13.0, released in June 2015, relies on older versions of dependencies, like depd at ~1.0.1, escape-html at 1.0.2, and range-parser at ~1.0.2. Its development dependencies are also older, indicating a less up-to-date testing and development environment.
For developers, opting for send version 0.13.1 is generally advisable due to its more recent dependencies and the likely inclusion of bug fixes and security patches, ensuring a more robust and reliable static file serving solution. This decision provides benefits related to better performance, enhanced security, and updated code compatibility.
All the vulnerabilities related to the version 0.13.1 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.
