Allow external scripts required by reader

The new CSP restricts script-src to 'self', but reader.html still loads DOMPurify from https://cdn.jsdelivr.net/... (and gtag from https://www.googletagmanager.com). Browsers enforcing CSP will block those scripts, so when the inline script later calls DOMPurify.sanitize(...) it throws a ReferenceError and breaks the article view for typical URLs that include source/tags. Consider whitelisting the required CDN origins in script-src or self-hosting those scripts so the sanitizer is available.

vercel.json

+  "functions": {
+    "src/aggregator.js": {
+      "maxDuration": 300,
+      "memory": 1024


The function memory allocation of 1024 MB (1 GB) seems excessive for an RSS aggregator function. Consider starting with a lower value like 512 MB or 256 MB and scaling up only if needed, as this will reduce costs and resource usage.

Suggested change

"memory": 1024

"memory": 512

src/aggregator.js

+function htmlEscape(input) {
+  if (!input) {
+    return '';
+  }
+  return input
+    .replace(/&/g, '&amp;')
+    .replace(/</g, '&lt;')
+    .replace(/>/g, '&gt;');


The htmlEscape function is incomplete. It only escapes &, <, and > characters but doesn't handle other important HTML entities like quotes (" and '). This could lead to XSS vulnerabilities in attribute contexts. Consider adding escaping for quotes: .replace(/"/g, '"') and .replace(/'/g, ''')

reader.html

 <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
+    <meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com; frame-src *; connect-src 'self'; img-src 'self' data: https:">


The Content-Security-Policy allows 'unsafe-inline' for both script-src and style-src, which significantly weakens the CSP protection against XSS attacks. Consider using nonces or hashes for inline scripts/styles, or move inline code to external files. Additionally, 'frame-src *' allows iframes from any source which may be too permissive.

vercel.json

+          "key": "X-XSS-Protection",
+          "value": "1; mode=block"


The X-XSS-Protection header is deprecated and should be removed. Modern browsers have removed support for this header, and it can actually introduce security vulnerabilities in older browsers. The Content-Security-Policy header provides better XSS protection.

Suggested change

"key": "X-XSS-Protection",

"value": "1; mode=block"

"key": "Content-Security-Policy",

"value": "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"

vercel.json

+      "use": "@vercel/static"
+    },
+    {
+      "src": "*.js",


Using "@vercel/static" for "*.js" files will serve all JavaScript files as static assets, which may not be the intended behavior. This could expose server-side JavaScript files that should not be publicly accessible. Consider being more specific about which JS files should be served statically (e.g., only files in a specific public directory).

Suggested change

"src": "*.js",

"src": "public/*.js",

src/aggregator.js

+  // Use DOMPurify to safely remove all HTML/script tags - prevents incomplete sanitization attacks
+  const cleanTitle = DOMPurify.sanitize(article.title || '', { ALLOWED_TAGS: [] });
+  const cleanSummary = DOMPurify.sanitize(article.contentSnippet || '', { ALLOWED_TAGS: [] });

  return {
-    title: article.title?.replace(/<[^>]*>/g, '').slice(0, 200) || 'Untitled',
-    link: addUTMParams(article.link, category),  // UTM tracks traffic FROM AI-Pulse
+    title: htmlEscape(cleanTitle).slice(0, 200) || 'Untitled',
+    link: article.link,  // Direct link, no tracking
    pubDate: new Date(article.pubDate || Date.now()),
    source: sourceName,
    tags: tags,
    category: article.categories?.[0] || 'General',
-    summary: smartTruncate(rawSummary, 600)  // Increased to 600 with smart truncation for better article previews
+    summary: smartTruncate(htmlEscape(cleanSummary), 600)  // DOMPurify removes tags, htmlEscape handles entities


Applying htmlEscape after DOMPurify.sanitize with ALLOWED_TAGS: [] may result in double-escaping. DOMPurify with ALLOWED_TAGS: [] already converts HTML to text content, so applying htmlEscape afterward will escape already-safe text. This could display escaped entities like & to users instead of &. Consider removing htmlEscape here or using only DOMPurify.

src/aggregator.js

+// Article links for external sources
+function getArticleLink(url, category = 'general') {
+  // Return direct link without any tracking parameters
+  // Users can add their own UTM if needed
+  return url;
+}
+


The function getArticleLink is defined but never used in the code. Since it only returns the URL unchanged, consider removing this unused function to improve code maintainability.

Suggested change

// Article links for external sources

function getArticleLink(url, category = 'general') {

// Return direct link without any tracking parameters

// Users can add their own UTM if needed

return url;

}
