EJS (Embedded JavaScript) is a simple templating engine that lets you generate HTML markup with plain JavaScript. Versions 2.4.1 and 2.4.2 offer comparable functionality for developers seeking an efficient way to embed dynamic content into their web applications. Both are lightweight and depend on no external runtime dependencies, making them easy to integrate. They include identical development dependencies like Jake for build tasks, JSDoc for documentation, Mocha for testing, Rimraf for file removal, Istanbul for test coverage, Lru-cache and Uglify-js for performance and Browserify.
The critical difference lies in EJS 2.4.2 being a newer iteration, released on May 24, 2016, succeeding version 2.4.1, published on January 24, 2016. While the data doesn't provide explicit details about the code-level changes, the release of a new version strongly suggests potential bug fixes, performance enhancements, or minor feature additions. Developers should look for patch notes or a changelog associated with version 2.4.2 to understand those specific improvements. If you require a stable, well-tested templating solution, and do not face any known issues on version 2.4.1, upgrading to 2.4.2 should result in better stability.
All the vulnerabilities related to the version 2.4.2 of the package

ejs lacks certain pollution protection
The ejs (aka Embedded JavaScript templates) package before 3.1.10 for Node.js lacks certain pollution protection.
mde ejs vulnerable to XSS
nodejs ejs version older than 2.5.5 is vulnerable to a Cross-site-scripting in the ejs.renderFile()
resulting in code injection
ejs template injection vulnerability
The ejs (aka Embedded JavaScript templates) package 3.1.6 for Node.js allows server-side template injection in settings[view options][outputFunctionName]. This is parsed as an internal option, and overwrites the outputFunctionName option with an arbitrary OS command (which is executed upon template compilation).
