Telejson is a valuable utility for developers needing to serialize and deserialize complex data structures, effectively "teleporting" them between different environments or processes. Versions 3.0.2 and 3.0.3 share a common core, built around dependencies like lodash, is-regex, isobject, is-symbol, is-function, and memoizerific, ensuring a solid foundation for handling diverse data types including regular expressions, symbols and leveraging memoization techniques. These dependencies allows developers to seamlessly move data containing complex data types where standard JSON serialization fails.
Looking at the differences, version 3.0.3 boasts a slightly reduced unpackedSize (39900 versus 45203), hinting to a potential optimization. Furthermore, the fileCount decreased from 16 to 14, suggesting some internal structural changes, be it removal of redundant files or aggregation of functionalities. Examining release dates, version 3.0.3 was released only approximately one day after version 3.0.2 implying that the update was a hotfix or minor improvement.
Developers considering telejson should prioritize version 3.0.3 for its optimized footprint and potential refinements. Both versions utilizes a MIT license meaning it can be leveraged within a broader range of projects, both open source and commercial and the code is hosted on github. The updates between the versions seem marginal but it is best practice to choose the latest version.
All the vulnerabilities related to the version 3.0.3 of the package
min-document vulnerable to prototype pollution
A vulnerability exists in the 'min-document' package prior to version 2.19.0, stemming from improper handling of namespace operations in the removeAttributeNS method. By processing malicious input involving the proto property, an attacker can manipulate the prototype chain of JavaScript objects, leading to denial of service or arbitrary code execution. This issue arises from insufficient validation of attribute namespace removal operations, allowing unintended modification of critical object prototypes. The vulnerability remains unaddressed in the latest available version.
