Review SummaryThis PR addresses a legitimate security vulnerability (incomplete multi-character sanitization) by implementing a loop-based approach to repeatedly remove ✅ Positive Aspects

}🛡️ Security Analysis
⚡ Performance Considerations
🔧 Minor Suggestions
🧪 Test Coverage RecommendationConsider adding unit tests for edge cases: // Test cases to add:
- Nested script tags: `<scr<script>ipt>alert('xss')</script>`
- Mixed case: `<SCRIPT>alert('xss')</SCRIPT>`
- Malformed tags: `<script>alert('xss')<script>`
- Multiple iterations needed📊 Overall Assessment
✅ Recommendation: ApproveThis is a solid security fix that effectively addresses the scanning alert. The implementation is clean, secure, and maintains existing functionality while fixing the vulnerability. The iterative approach is the correct solution for handling incomplete multi-character sanitization, and the code quality is good. The minor suggestions above are optional improvements but not blockers. |

🎯 Review SummaryThis PR addresses a legitimate security vulnerability by implementing a superior solution using the ✅ Excellent Security FixFile: private extractTextContent(html: string): string {
const sanitized = sanitizeHtml(html, {
allowedTags: false,
disallowedTagsMode: 'discard',
exclusiveFilter: (frame) => {
return frame.tag === 'script' || frame.tag === 'style';
}
});
return sanitized
.replace(/<[^>]*>/g, ' ')
.replace(/\s+/g, ' ')
.trim();
}Security Benefits:
🔧 Minor Optimization SuggestionThe current configuration has some redundancy. Consider simplifying: private extractTextContent(html: string): string {
const sanitized = sanitizeHtml(html, {
allowedTags: [], // More explicit than false
allowedAttributes: {},
disallowedTagsMode: 'discard'
// exclusiveFilter not needed since we're removing all tags anyway
});
return sanitized
.replace(/\s+/g, ' ')
.trim();
}Rationale: Since 🚨 GitHub Security AlertsThe security scanner is still flagging issues, but these appear to be false positives given the new implementation:

Potential fix for https://github.com/otdoges/zapdev/security/code-scanning/122
The best way to fix this problem is to use a well-tested HTML sanitization library, such as
sanitize-html, to reliably remove all<script>and<style>tags and their content, as well as any other potentially dangerous HTML. However, if adding a dependency is not an option, a safer alternative is to repeatedly apply the regular expression replacements for<script>and<style>tags until no more matches are found. This ensures that all instances, including those that may appear after previous replacements, are removed.To implement this fix in
src/lib/search-service.ts, update theextractTextContentmethod (lines 318-325) to repeatedly remove<script>and<style>tags and their content until none remain, before proceeding to strip all other tags and whitespace. No new imports are needed for the repeated replacement approach.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
