Brace expansion, a utility mirroring the brace expansion capabilities found in shells like sh and bash, offers developers a convenient way to generate string combinations. Comparing versions 1.1.7 and 1.1.8 reveals a subtle but significant change in their dependencies. Both versions rely on concat-map version 0.0.1 and share the same development dependencies for testing (tape and matcha). However, the crucial difference lies in the balanced-match dependency. Version 1.1.7 depends on balanced-match version 0.4.1, while version 1.1.8 upgrades this dependency to ^1.0.0.
This upgrade to balanced-match is the primary change, suggesting potential bug fixes, performance improvements, or new features introduced within the balanced-match library itself. Developers should investigate the changes within balanced-match between versions 0.4.1 and 1.0.0 to understand the specific implications for their projects. If your project specifically relies on the older balanced-match behavior, version 1.1.7 might be preferable. However, for most use cases, upgrading to the newer brace-expansion 1.1.8 is recommended to leverage the improvements and potential security fixes included in the updated dependency. The MIT license remains consistent across both versions, providing developers with the freedom to use and modify the library as needed. Both libraries were created by Julian Gruber.

brace-expansion Regular Expression Denial of Service vulnerability
A vulnerability was found in juliangruber brace-expansion up to 1.1.11/2.0.1/3.0.0/4.0.0. It has been rated as problematic. Affected by this issue is the function expand of the file index.js. The manipulation leads to inefficient regular expression complexity. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 1.1.12, 2.0.2, 3.0.1 and 4.0.1 is able to address this issue. The name of the patch is a5b98a4f30d7813266b221435e1eaaf25a1b0ac5. It is recommended to upgrade the affected component.
