The negotiator package, a lightweight library for HTTP content negotiation, saw a subtle but important update between versions 0.4.5 and 0.4.6. Both versions, licensed under the MIT license and maintained by Federico Romero, focus on providing efficient and standards-compliant content negotiation capabilities for Node.js applications. Developers can leverage this package to determine the best content type, language, or encoding to serve to a client based on the client's Accept headers.
The core functionality remains consistent: offering robust parsing of HTTP Accept headers and algorithms for determining the client's preferred options. The package boasts zero dependencies, making it a lean and attractive choice for minimizing project bloat. With only nodeunit listed as a dev dependency, the focus clearly remains on core functionality and simplicity.
The key difference lies in the timing of the releases, with version 0.4.6 released on June 11, 2014, roughly two weeks after version 0.4.5 (May 29, 2014). While the provided data doesn't explicitly detail the specific changes incorporated in 0.4.6, the relatively short interval suggests that it likely included bug fixes, minor performance improvements, or updates to align with evolving interpretations of HTTP content negotiation standards. Developers should consider checking the project's commit history on GitHub to understand the exact refinements made in version 0.4.6. Although seemingly minor, these small improvements are the keystone for building reliable web applications and APIs.
All the vulnerabilities related to the version 0.4.6 of the package
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.
