Eslint is a powerful JavaScript linting tool designed to help developers identify and fix code quality issues. Comparing versions 0.1.1 and 0.1.0 reveals a subtle but important update concerning the release date. Version 0.1.1 was released on November 10, 2013, while version 0.1.0 was released on November 4, 2013, indicating a quick patch or minor enhancement within a week.
Beyond the release date, the core dependencies and development dependencies remain consistent. Both versions rely on crucial libraries such as escope for scope analysis, jshint for general linting, esprima for JavaScript parsing, optimist for command-line argument parsing, and estraverse for AST traversal. For development, vows handles testing, sinon provides mocking capabilities, jshint offers further linting during development, istanbul covers code coverage, and commonjs-everywhere aids in CommonJS module compatibility.
The consistent dependency structure suggests that version 0.1.1 isn't a major overhaul but likely addresses bug fixes or minor improvements. The MIT license ensures developers have the freedom to use and modify the code, and the GitHub repository URL guarantees community collaboration. Developers should prioritize the latest minor version to benefit from the newest fixes. To adopt Eslint, you can integrate it into project workflow to automatically flag potential errors while developing, enforcing coding standards and style guidelines.
All the vulnerabilities related to the version 0.1.1 of the package
Prototype Pollution in minimist
Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
