The initial release of the debug package, version 0.0.1, marks the genesis of a now widely-used debugging utility for Node.js and browser-based JavaScript development. Described simply as a "small debugging utility," this version laid the groundwork for its successors. Examining its metadata reveals a very lightweight initial footprint – a testament to its core philosophy. The declared dependencies are empty, hinting at a self-contained implementation, relying perhaps on fundamental JavaScript capabilities. For developers intrigued by minimal dependencies and foundational code, this version offers a glimpse into streamlined early JavaScript package design.
The inclusion of "mocha" as a dev dependency signals an intent to employ unit testing from the outset, a positive indicator of coding best practices. This demonstrates a commitment to quality, even in the nascent stages.
Comparing this against the *previous stable version* which is unknown from the data implies significant evolution. One can infer later versions likely introduced features, addressed bugs, or optimized performance based on community feedback. This original offering, however, serves as a valuable study for understanding the roots of a ubiquitous tool that has assisted countless developers. The absence of dependencies makes it an accessible starting point for understanding how simple debugging tools can be built. Finally, for developers who want to inspect the evolution path of debug, this version provides access to the original approach used by TJ Holowaychuk to implement this indispensable NPM package.
All the vulnerabilities related to the version 0.0.1 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.
