Path-to-regexp offers a straightforward way for developers to convert route paths, similar to those used in Express.js, into regular expressions. These expressions are crucial for matching URLs and extracting parameters, simplifying routing logic in web applications. Comparing version 0.1.10 with its predecessor, 0.1.9, reveals subtle but potentially important distinctions.
Both versions maintain the same core functionality and development dependencies, relying on Mocha for testing and Istanbul for code coverage. They are licensed under the MIT license, promoting open and permissive usage. A key difference lies in the repository URL; version 0.1.10 points to github.com/pillarjs/path-to-regexp, while version 0.1.9 references github.com/component/path-to-regexp. This change in repository suggests a potential shift in maintainership or project organization.
The unpacked size also differs slightly, with version 0.1.10 being marginally larger at 6376 bytes compared to version 0.1.9's 6210 bytes. While seemingly insignificant, this increase could indicate minor code additions, bug fixes, or performance improvements. The most recent version was released in September 2024 while the previous stable version was released at the end of August 2024. Developers should evaluate the newer version for potential benefits or compatibility issues before upgrading, particularly regarding the repository change and any subtle behavioral differences stemming from the size increase. Always check the release notes for detailed changes.
All the vulnerabilities related to the version 0.1.10 of the package
path-to-regexp contains a ReDoS
The regular expression that is vulnerable to backtracking can be generated in versions before 0.1.12 of path-to-regexp, originally reported in CVE-2024-45296
Upgrade to 0.1.12.
Avoid using two parameters within a single path segment, when the separator is not . (e.g. no /:a-:b). Alternatively, you can define the regex used for both parameters and ensure they do not overlap to allow backtracking.
