Mocha 9.1.0 refines the popular JavaScript testing framework, building upon the solid foundation of version 9.0.3. Both versions offer a simple, flexible, and fun environment for test-driven development, but subtle changes enhance the developer experience. Examining the devDependencies, we can observe a shift in the tooling ecosystem. Mocha 9.1.0 upgrades @babel/preset-env to version 7.14.8 from 7.12.17 in 9.0.3 and removes @babel/runtime . Developers leveraging Babel for transpilation will benefit from the updated preset, potentially gaining access to newer language features and optimizations. Furthermore, important to notice is the removal of regenerator-transform and @babel/plugin-transform-regenerator potentially simplifying the babel compilation process. The absence of these indicates changes in the Babel configuration, where regenerator might be included by default now.
The upgrade to eslint from 7.8.1 to 7.8.1, and webpack remains stable, indicating consistency within the core build and linting processes. Developers relying on these tools for code quality and bundling can expect familiar behavior. These incremental improvements, while seemingly minor, collectively contribute to a more streamlined and modern development workflow for Mocha users. The core testing experience remains consistent, ensuring existing test suites remain compatible, while the updated dependencies position developers to leverage the latest advancements in JavaScript development.
All the vulnerabilities related to the version 9.1.0 of the package
Exposure of Sensitive Information to an Unauthorized Actor in nanoid
The package nanoid from 3.0.0, before 3.1.31, are vulnerable to Information Exposure via the valueOf() function which allows to reproduce the last id generated.
Predictable results in nanoid generation when given non-integer values
When nanoid is called with a fractional value, there were a number of undesirable effects:
Version 3.3.8 and 5.0.9 are fixed.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
Cross-site Scripting (XSS) in serialize-javascript
A flaw was found in npm-serialize-javascript. The vulnerability occurs because the serialize-javascript module does not properly sanitize certain inputs, such as regex or other JavaScript object types, allowing an attacker to inject malicious code. This code could be executed when deserialized by a web browser, causing Cross-site scripting (XSS) attacks. This issue is critical in environments where serialized data is sent to web clients, potentially compromising the security of the website or web application using this package.
