Add support for wildcard patterns in import/core-modules setting, allowing * to match multiple modules like @my-monorepo/* or @My-*/*. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Prevent '*' pattern from matching all modules, which would disable dependency analysis and create security vulnerabilities. - Add safety check for bare wildcard patterns - Add comprehensive test coverage for security edge cases - Ensure valid wildcard patterns still work correctly
Enhance security validation to catch a broader range of dangerous wildcard patterns that could disable dependency analysis: - Block double wildcards (**) - Block overly broad patterns (*/*) - Block regex-style wildcards (.*) - Block patterns that are too short and broad (a*, *a) - Block multiple wildcards except for valid @namespace/* patterns - Add comprehensive test coverage for all dangerous patterns - Maintain support for legitimate use cases This prevents accidental or malicious disabling of ESLint's dependency analysis while preserving intended functionality.
Allow legitimate multi-wildcard patterns like @My-*/* while still blocking dangerous patterns: - Allow @namespace/* patterns (including @My-*/* style patterns) - Block dangerous patterns like *foo*, foo*bar*, */*/* - Fix regex escaping issue - Update comprehensive test coverage - All 2996 tests now pass

There was a problem hiding this comment.
do we need this function at all now that it's just using minimatch?
