PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Arbitrary URL fetch Description: The new source-map resolution logic fetches JavaScript and sourcemap URLs derived from stack-trace text (processStackLine() → getSourceMapConsumer() → fetchWithRetry()), so if a page can influence error.stack (e.g., by throwing an Error with a crafted/writable stack string) the extension may be coerced into making arbitrary network requests (SSRF-like behavior, including potential access to internal/localhost resources depending on extension/network permissions). sourceMapper.js [36-121] Referred Code async processStackLine(line) { const match = line.match(/at\s+(?:.*\s+\()?(.*):(\d+):(\d+)\)?/); if (!match) return line; const [, filename, lineNo, colNo] = match; // Do not try to map extension internal files if (filename && filename.startsWith('chrome-extension://')) return line; try { const consumer = await this.getSourceMapConsumer(filename); if (!consumer) return line; const pos = { line: parseInt(lineNo, 10), column: parseInt(colNo, 10) }; const originalPosition = consumer.originalPositionFor(pos); if (originalPosition.source) { const { source, line: origLine, column: origCol, name } = originalPosition; const sourcePath = new URL(source, filename).href; return ` at ${name || 'anonymous'} (${sourcePath}:${origLine}:${origCol})`; } } catch (e) { ... (clipped 65 lines)
	Stored XSS Description: renderList() uses listItem.innerHTML = </code>${item}...<code> with unescaped user-controlled values (domains/ignored patterns), enabling stored XSS in the extension options page if an attacker can inject values into settings.domainList/settings.ignoredPatterns (e.g., via synced storage poisoning or another extension/component writing settings), leading to script execution in the extension page context. settings.js [61-75] Referred Code function renderList(list, listElement, noItemsMessage, itemClass, dataAttribute, removeItemFn) { listElement.innerHTML = ''; noItemsMessage.style.display = list.length === 0 ? 'block' : 'none'; list.forEach(item => { const listItem = document.createElement('li'); listItem.className = itemClass; listItem.innerHTML = `<span>${item}</span><button class="remove-btn" data-${dataAttribute}="${item}">Remove</button>`; listElement.appendChild(listItem); }); listElement.querySelectorAll('.remove-btn').forEach(button => { button.addEventListener('click', () => removeItemFn(button.dataset[dataAttribute])); }); }

Custom Compliance
🟢	Generic: Meaningful Naming and Self-Documenting Code Objective: Ensure all identifiers clearly express their purpose and intent, making code self-documenting Status: Passed Learn more about managing compliance generic rules or creating your own custom rules
🔴	Generic: Security-First Input Validation and Data Handling Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent vulnerabilities Status: DOM XSS risk: User-controlled values (domains/patterns) are inserted into the settings page DOM via innerHTML without escaping/sanitization, enabling HTML/JS injection in the extension context. Referred Code function renderList(list, listElement, noItemsMessage, itemClass, dataAttribute, removeItemFn) { listElement.innerHTML = ''; noItemsMessage.style.display = list.length === 0 ? 'block' : 'none'; list.forEach(item => { const listItem = document.createElement('li'); listItem.className = itemClass; listItem.innerHTML = `<span>${item}</span><button class="remove-btn" data-${dataAttribute}="${item}">Remove</button>`; listElement.appendChild(listItem); }); Learn more about managing compliance generic rules or creating your own custom rules
⚪	Generic: Comprehensive Audit Trails Objective: To create a detailed and reliable record of critical system actions for security analysis and compliance. Status: No audit logging: The new message dispatcher performs settings changes and error-count state mutations without emitting any audit log entries that would allow reconstruction of who/when/what/Outcome. Referred Code function handleMessage(message, sender, sendResponse) { const actions = { getSettings: () => sendResponse({ settings: settingsManager.getSettings() }), updateSettings: async (msg) => { await settingsManager.updateSettings(msg.settings); const tabs = await chrome.tabs.query({}); for (const tab of tabs) { chrome.tabs.sendMessage(tab.id, { action: 'settingsUpdated', settings: settingsManager.getSettings() }).catch(() => {}); } sendResponse({ success: true }); }, resetSettings: async () => { const defaultSettings = await settingsManager.resetSettings(); const tabs = await chrome.tabs.query({}); for (const tab of tabs) { chrome.tabs.sendMessage(tab.id, { action: 'settingsUpdated', settings: defaultSettings }).catch(() => {}); } sendResponse({ success: true, settings: defaultSettings }); }, errorDetected: (msg, sndr) => { if (!sndr.tab) return; ...

	Generic: Robust Error Handling and Edge Case Management Objective: Ensure comprehensive error handling that provides meaningful context and graceful degradation Status: Swallowed exceptions: Source map processing and per-line mapping failures are silently swallowed (commented logging), which may hinder production debugging and makes failures non-actionable. Referred Code async processStackLine(line) { const match = line.match(/at\s+(?:.*\s+\()?(.*):(\d+):(\d+)\)?/); if (!match) return line; const [, filename, lineNo, colNo] = match; // Do not try to map extension internal files if (filename && filename.startsWith('chrome-extension://')) return line; try { const consumer = await this.getSourceMapConsumer(filename); if (!consumer) return line; const pos = { line: parseInt(lineNo, 10), column: parseInt(colNo, 10) }; const originalPosition = consumer.originalPositionFor(pos); if (originalPosition.source) { const { source, line: origLine, column: origCol, name } = originalPosition; const sourcePath = new URL(source, filename).href; return ` at ${name || 'anonymous'} (${sourcePath}:${origLine}:${origCol})`; } } catch (e) { ... (clipped 35 lines) Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Secure Error Handling Objective: To prevent the leakage of sensitive system information through error messages while providing sufficient detail for internal debugging. Status: Stack trace exposed: The popup UI renders full stack traces directly to the user (escaped but complete), which may expose sensitive implementation details depending on the deployment and threat model. Referred Code function showErrorDetails(error) { if (!error) { ui.errorDetails.style.display = 'none'; return; } let detailsHtml = ` <div class="error-details-section"> <h3>Error Message</h3> <div class="error-message-full">${escapeHtml(error.message)}</div> </div>`; if (error.stack) { detailsHtml += ` <div class="error-details-section"> <h3>Stack Trace</h3> <div class="stack-trace"><pre>${escapeHtml(error.stack)}</pre></div> </div>`; } Learn more about managing compliance generic rules or creating your own custom rules
	Generic: Secure Logging Practices Objective: To ensure logs are useful for debugging and auditing without exposing sensitive information like PII, PHI, or cardholder data. Status: Unstructured console logs: Handler exceptions are logged via console.error with raw error objects, which is unstructured and could include sensitive data depending on the thrown error contents. Referred Code notifyHandlers(error) { this.errorHandlers.forEach(handler => { try { handler(error); } catch (e) { console.error('Error in JSErrorFlow error handler:', e); } }); Learn more about managing compliance generic rules or creating your own custom rules

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Restore removed domain normalization logic Restore the domain normalization logic in the addDomain function to ensure that URLs with different protocols or paths are correctly treated as the same domain. extension/js/settings.js [80-88] +function normalizeDomain(domain) { + try { + // Handle cases where user enters a full URL + if (!domain.startsWith('http')) { + domain = `https://${domain}`; + } + return new URL(domain).hostname; + } catch (e) { + // Fallback for simple hostnames without protocol + return domain.split('/')[0].split(':')[0]; + } +} + function addDomain() { const domain = ui.domainInput.value.trim(); - if (domain && !settings.domainList.includes(domain)) { - settings.domainList.push(domain); - renderDomainList(); - ui.domainInput.value = ''; - hasUnsavedChanges = true; + if (domain) { + const normalizedDomain = normalizeDomain(domain); + if (normalizedDomain && !settings.domainList.includes(normalizedDomain)) { + settings.domainList.push(normalizedDomain); + renderDomainList(); + ui.domainInput.value = ''; + hasUnsavedChanges = true; + } } } Apply / Chat Suggestion importance[1-10]: 9 __ Why: This suggestion identifies a critical regression where domain normalization was removed, which would break the domain filtering feature. Restoring this logic is essential for correctness.	High
	Clear stale errors on load failure In the loadErrors function, clear the state.errors array within the catch block to prevent displaying stale error data when loading fails. extension/js/popup.js [69-81] async function loadErrors() { try { const response = await chrome.tabs.sendMessage(state.activeTabId, { action: 'getErrors' }); state.errors = response?.errors || []; - renderErrorList(); } catch (e) { + state.errors = []; // Clear stale errors ui.noErrorsMessage.textContent = "No errors detected on this page."; if (e.message.includes("Receiving end does not exist")) { ui.noErrorsMessage.innerHTML = "JSErrorFlow is not active on this page. <br> Try reloading the page."; } - renderErrorList(); } + renderErrorList(); } Apply / Chat Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies a UI bug where stale data is shown on error, which is confusing for the user. The fix is simple and correct.	Medium
	Avoid installing dependencies within scripts Modify ensurePackageInstalled to exit with an error if a dependency is missing, instead of automatically installing it, to prevent side effects and ensure a consistent environment. scripts/create-icons.js [33-42] function ensurePackageInstalled(packageName) { try { require.resolve(packageName); - console.log(`✅ ${packageName} is already installed.`); } catch (error) { - console.log(`Installing ${packageName}...`); - execSync(`npm install ${packageName} --save-dev`); - console.log(`✅ ${packageName} installed successfully.`); + console.error(`❌ Error: The '${packageName}' package is not installed.`); + console.error(`Please run 'npm install' to install all required dependencies.`); + process.exit(1); } } Apply / Chat Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies that build scripts should not have side effects like installing dependencies, which can lead to inconsistent environments. The proposed change improves the script's robustness and aligns with best practices.	Medium
	Fix incorrect 3-digit hex parsing Add support for 3-digit shorthand hex color codes in the hexToRgba function by expanding them to their 6-digit equivalent before parsing. extension/js/modules/highlighter.js [235-240] hexToRgba(hex, opacity) { - const r = parseInt(hex.slice(1, 3), 16) || 0; - const g = parseInt(hex.slice(3, 5), 16) || 0; - const b = parseInt(hex.slice(5, 7), 16) || 0; + let c = hex.substring(1); // strip # + if (c.length === 3) { + c = c.split('').map(char => char + char).join(''); + } + if (c.length !== 6) { + return `rgba(0, 0, 0, ${opacity})`; // Return a default for invalid hex + } + const r = parseInt(c.substring(0, 2), 16) || 0; + const g = parseInt(c.substring(2, 4), 16) || 0; + const b = parseInt(c.substring(4, 6), 16) || 0; return `rgba(${r}, ${g}, ${b}, ${opacity})`; } Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion correctly identifies a bug in parsing 3-digit hex color codes and provides a robust fix, improving the user-configurable highlight feature.

General	Improve object serialization in console errors In overrideConsoleError, use JSON.stringify to serialize object arguments for more informative error messages, preventing them from becoming "[object Object]". extension/js/modules/errorCapturer.js [114] -const message = args.map(arg => arg instanceof Error ? arg.message : String(arg)).join(' '); +const message = args.map(arg => { + if (arg instanceof Error) return arg.message; + if (typeof arg === 'object' && arg !== null) { + try { + return JSON.stringify(arg); + } catch (e) { + // Fallback for circular references or other stringify errors + } + } + return String(arg); + }).join(' '); Apply / Chat Suggestion importance[1-10]: 8 __ Why: This suggestion fixes a regression introduced in the PR where logged objects become uninformative "[object Object]" strings. The proposed change significantly improves the usefulness of the console error capturing feature by properly serializing objects.	Medium
	Include original Error instance Add the errorInstance to the captured console error object under the error property to ensure a consistent data structure across all error types. extension/js/modules/errorCapturer.js [108-123] -overrideConsoleError() { - const originalConsoleError = console.error; - console.error = (...args) => { - originalConsoleError.apply(console, args); - if (!this.isEnabled) return; - const message = args.map(arg => arg instanceof Error ? arg.message : String(arg)).join(' '); - const errorInstance = args.find(arg => arg instanceof Error) || new Error(message); - const error = { - type: 'console', - message, - stack: errorInstance.stack || new Error().stack, - timestamp: new Date().toISOString(), - count: 1, - }; +const error = { + type: 'console', + message, + error: errorInstance, + stack: errorInstance.stack || new Error().stack, + timestamp: new Date().toISOString(), + count: 1, +}; [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 5 __ Why: The suggestion correctly points out an inconsistency in the error object structure for console errors compared to runtime and promise errors. Adding the error property makes the data model more consistent for handlers.	Low
