Potential fix for https://github.com/Angular-Wave/angular.ts/security/code-scanning/451

To fix the problem, we need to modify the regular expression to remove the ambiguity that causes exponential backtracking. Specifically, we can replace the ambiguous part [^{}\\]+ with a more precise pattern that avoids nested quantifiers and alternations.

  • We will update the regular expression on line 212 to use a non-capturing group and a more specific pattern to match the intended characters without causing backtracking issues.
  • The changes will be made in the file src/router/url/url-matcher.js.
