Fixes https://github.com/IgniteUI/ignite-ui/security/code-scanning/26
To fix the problem, we need to modify the regular expression to remove the ambiguity that leads to exponential backtracking. Specifically, we should avoid nested quantifiers and ensure that each part of the regular expression can only match in one way.
The problematic part
[\w\$\-]+(\.|\s)?[\w\$\-]*can be restructured to avoid nested quantifiers. We can achieve this by breaking down the pattern into more specific parts that do not overlap in their matching capabilities.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
