Resolve merge conflicts in PR #12: Dependabot security fixes #14

Copilot · 2026-01-08T20:46:49Z

User description

PR #12 had merge conflicts with master preventing merge. Conflicts arose from parallel changes to dependency management and ExcelJS migration in both branches.

Resolved Conflicts

package.json: Two conflict zones

Removed @angular/cli from dependencies (duplicate with devDependencies)
Merged npm overrides: kept both security fixes (axios, form-data) and type definition pins (@types/d3-dispatch, @types/linkify-it)

mapping.component.ts: Single conflict at line 186

Preserved optional chaining column.eachCell?.() required for TypeScript 4.6

package-lock.json: Extensive conflicts

Regenerated via npm install after resolving package.json

Result

All PR #12 security improvements intact:

CSP headers, security audit utility, ExcelJS migration
npm overrides for axios ≥1.8.2 (SSRF), form-data ≥4.0.4 (boundary prediction)
Type definition pins for TS 4.6 compatibility

Ready for merge.

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	URL sanitization bypass Description: `SecurityAudit.isSafeUrl()` only blocks a small set of protocol prefixes via `startsWith()`, which can potentially be bypassed with crafted URLs that browsers may still interpret as executable (e.g., `java\tscript:...`, `java\nscript:...`, mixed/embedded control characters, or other parsing edge cases), leading to XSS if `sanitizeUrl()` output is used for `href`/`xlink:href` bindings. security-audit.ts [10-24] Referred Code static isSafeUrl(url: string): boolean { if (!url \|\| typeof url !== 'string') return false; const dangerous = ['javascript:', 'data:', 'vbscript:', 'file:']; const lowerUrl = url.trim().toLowerCase(); return !dangerous.some(protocol => lowerUrl.startsWith(protocol)); } /** * Sanitizes a URL for safe use, returns empty string if dangerous */ static sanitizeUrl(url: string): string { return this.isSafeUrl(url) ? url : ''; }
	Weak Content Security Policy Description: The CSP explicitly allows `'unsafe-inline'` and `'unsafe-eval'` in `script-src`, which substantially weakens XSS protections (inline script execution and eval-like sinks remain usable), so this mitigation may provide limited defense if an injection is found elsewhere in the app. index.html [8-20] Referred Code <!-- Content Security Policy for XSS mitigation (Dependabot #58) Note: 'unsafe-inline' and 'unsafe-eval' are required for Angular 13. These will be removed when upgrading to Angular 19+ which supports stricter CSP. --> <meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com https://cdnjs.cloudflare.com; img-src 'self' data: https:; font-src 'self' data: https://fonts.gstatic.com; connect-src 'self' https:; object-src 'none'; base-uri 'self';" />

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Security	Strengthen URL validation against XSS Improve the URL validation in `isSafeUrl` to prevent XSS bypasses. Normalize the URL by removing control characters and whitespace before checking for dangerous protocols. src/app/util/security-audit.ts [14-16] -const lowerUrl = url.trim().toLowerCase(); +// Normalize by removing control characters and whitespace, then convert to lower case. +const normalizedUrl = url.replace(/[\s\u0000-\u001f]/g, '').toLowerCase(); -return !dangerous.some(protocol => lowerUrl.startsWith(protocol)); +return !dangerous.some(protocol => normalizedUrl.startsWith(protocol)); Apply / Chat Suggestion importance[1-10]: 9 __ Why: This suggestion addresses a valid and non-obvious XSS bypass technique by strengthening the new `isSafeUrl` function, making the PR's security fix significantly more robust.	High
Security	Tighten Content Security Policy rules Tighten the Content Security Policy by making the `img-src` directive more restrictive. Remove the overly permissive `https:` source to reduce the risk of loading unintended images. src/index.html [11-20] <meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com https://cdnjs.cloudflare.com; - img-src 'self' data: https:; + img-src 'self' data:; font-src 'self' data: https://fonts.gstatic.com; connect-src 'self' https:; object-src 'none'; base-uri 'self';" /> Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies that `img-src https:` is overly permissive and proposes a stricter policy, which is a valid security hardening improvement aligned with the PR's goals.	Low
High-level	Unused security utility adds dead code The new `SecurityAudit` class is unused within the codebase. It should either be integrated to perform URL sanitization or removed to eliminate dead code. Examples: src/app/util/security-audit.ts [1-25] /** * Security utility to validate URLs before binding to SVG/MathML attributes * Addresses Dependabot Alert #58 (Angular XSS via SVG attributes) / export class SecurityAudit { /* * Validates that a URL is safe for use in href/xlink:href attributes * Blocks javascript:, data:, and other dangerous protocols */ static isSafeUrl(url: string): boolean { ... (clipped 15 lines) Solution Walkthrough: Before: // src/app/util/security-audit.ts (new file) export class SecurityAudit { static isSafeUrl(url: string): boolean { ... } static sanitizeUrl(url: string): string { ... } } // src/app/pages/circular-heatmap/circular-heatmap.component.ts ... // SECURITY NOTE: xlink:href usage here is safe... .attr('xlink:href', '#segment-label-path-' + id) ... // No other files import or use SecurityAudit. After: // Option 1: Remove the unused utility // File 'src/app/util/security-audit.ts' is deleted. // Option 2: Integrate the utility // src/app/pages/circular-heatmap/circular-heatmap.component.ts import { SecurityAudit } from 'src/app/util/security-audit'; ... .attr('xlink:href', SecurityAudit.sanitizeUrl('#segment-label-path-' + id)) ... Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies that the new `SecurityAudit` utility is dead code, which adds unnecessary complexity and maintenance overhead.	Low

src/app/util/security-audit.ts

+/**
+ * Security utility to validate URLs before binding to SVG/MathML attributes
+ * Addresses Dependabot Alert #58 (Angular XSS via SVG attributes)
+ */
+export class SecurityAudit {
+  /**
+   * Validates that a URL is safe for use in href/xlink:href attributes
+   * Blocks javascript:, data:, and other dangerous protocols
+   */
+  static isSafeUrl(url: string): boolean {
+    if (!url || typeof url !== 'string') return false;
+

+  static sanitizeUrl(url: string): string {

+  }
+}


The SecurityAudit utility class has been added but is not actually used anywhere in the codebase. While the class itself is well-implemented and provides good URL validation functionality, it should either be used for its intended purpose (validating URLs before binding to SVG/MathML attributes) or removed if not needed. Consider actually implementing the security checks in places where user-controlled URLs might be used with xlink:href or similar attributes.

src/index.html

+                   img-src 'self' data: https:; 
+                   font-src 'self' data: https://fonts.gstatic.com; 
+                   connect-src 'self' https:; 


The CSP header allows 'unsafe-inline' and 'unsafe-eval' which significantly weakens the security posture. While the comment explains this is required for Angular 13 and will be addressed in Angular 19+, the CSP also allows 'img-src' and 'connect-src' to any https: source, which is overly permissive. Consider restricting these to specific trusted domains rather than allowing all HTTPS sources to reduce attack surface.
