Fix Multiple Stored XSS Vulnerabilities in InvoicePlane 1.7.0

Fixed Vulnerabilities

  • Vulnerability 1: Family Name XSS - Fixed in application/modules/products/views/form.php (line 40)

    • Added htmlsc() encoding to $family->family_name
  • Vulnerability 2: Invoice Number XSS - Already fixed in codebase

    • All instances in application/modules/invoices/views/view.php (lines 247, 494)
    • All instances in application/modules/dashboard/views/index.php (line 233)
    • Already use htmlsc() encoding
  • Vulnerability 3: Product Unit Name XSS - Fixed in 4 locations:

    • application/modules/invoices/views/partial_itemlist_table.php (line 127)
    • application/modules/invoices/views/partial_itemlist_responsive.php (line 71)
    • application/modules/quotes/views/partial_itemlist_responsive.php (line 46)
    • application/modules/products/views/form.php (line 94)
    • Added htmlsc() encoding to both $unit->unit_name and $unit->unit_name_plrl
  • Additional: Email Template JavaScript Context XSS - Fixed in application/modules/email_templates/views/form.php (line 203)

    • Changed from string interpolation to json_encode() with security flags (JSON_HEX_TAG | JSON_HEX_AMP | JSON_HEX_APOS | JSON_HEX_QUOT)
  • Backend Input Sanitization - Fixed filter_input() bug in application/core/Admin_Controller.php

    • Fixed critical bug: now actually modifies POST data (was only modifying a copy)
    • Added XSS detection logging to application/logs/ with user ID, IP, timestamp, field names
    • Optimized logging: ip_address and user_agent logged once per request (not per field)
    • Strict comparison in in_array() checks to prevent type juggling vulnerabilities
    • Robust JSON encoding with error handling for invalid UTF-8
    • Bypasses sanitization for all password fields:
      • user_password, user_passwordv (user account passwords)
      • invoice_password (invoice PDF password protection)
      • quote_password (quote PDF password protection)
    • Bypasses HTML content: email_template_body
    • Recursive array sanitization with consistent bypass support
    • Consistent sanitization order: xss_clean() then strip_tags()
    • Avoids double-encoding: no html_escape() at input, only htmlsc() at output
    • Defense-in-depth: Both input sanitization AND output encoding

Defense-in-Depth Strategy

Input Layer (Backend):

  • filter_input() sanitizes all POST data with xss_clean() and strip_tags()
  • Logs XSS attempts with full context to application logs (optimized format)
  • Recursively sanitizes array values with same bypass rules
  • Bypasses: user_password, user_passwordv, invoice_password, quote_password, email_template_body

Output Layer (Frontend):

  • All user data escaped with htmlsc() in HTML contexts
  • JavaScript contexts use json_encode() with security flags

Security Model:

  • Input sanitization removes dangerous patterns
  • Output encoding prevents execution of any remaining content
  • Logging provides audit trail for security incidents
  • Strict type checking prevents bypass via type juggling

Files changed: 6 files total

  • 5 view templates (output encoding)
  • 1 core controller (input sanitization + logging)

💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.

I created 1 PR that fixes all 3 vulnerabilities from the security report together, rather than 3 separate PRs.

I've completed a comprehensive XSS audit of all view files and found one additional vulnerability:

Email Template JavaScript Context XSS - Fixed in commit 92caad2

  • File: application/modules/email_templates/views/form.php (line 203)
  • Changed from string interpolation to json_encode() for proper JavaScript context escaping

Audit Results:

  • ✅ All user-controlled text fields (names, descriptions, addresses, emails, phone numbers) are properly escaped with htmlsc() or form_value($field, true)
  • ✅ All textarea fields use proper escaping
  • ✅ All text input fields use proper escaping
  • ✅ Numeric IDs follow codebase pattern (not escaped as they're auto-increment integers)
  • ✅ JavaScript contexts now use json_encode() for safe output

Total files fixed: 5 files, 6 lines changed

@copilot shouldn't the XSS be caught in the backend as well?
Now you're letting it happen and just clean it during output.

I would like:

  • Each and every field that can receive an XSS to be cleaned from XSS, where appropriate
  • A log file to be written after XSS was cleaned
  • Careful with password fields, they need to be able to contain "'> etcetera

@copilot shouldn't the XSS be caught in the backend as well?

...

The codebase already has filter_input() in Admin_Controller that calls xss_clean(), strip_tags(), and html_escape() on input. However, there's a critical bug: it modifies a copy of $_POST, not the actual data, so it has no effect.

Two approaches for XSS protection:

  1. Output encoding (current fix): Safe, preserves user data, standard practice (OWASP recommended)
  2. Input sanitization: Can corrupt legitimate data (e.g., code snippets, math expressions like <>, foreign characters)

For your requirements:

  • Fixing the filter_input() bug will strip ALL HTML/special chars from fields, including passwords (breaks your requirement)
  • Adding per-field sanitization with logging requires identifying which fields need it vs which don't (passwords, descriptions with formatting, etc.)
  • Output encoding is defense-in-depth compatible with input validation

Question: Do you want me to fix the filter_input() bug and add logging, or keep output encoding? If fixing, should certain fields (passwords, descriptions) bypass sanitization?

  • Fix filter_input() bug. keep output encoding
  • Only bypass sanitization for password fields. And fields that can contain HTML like email templates.
  • Make sensible decisions

I don't want to be emailed in the middle of the night that another security vulnerability has been found

Fixed in commits b756c88 and 0fa0bdf:

Input Sanitization (Backend):

  • ✅ Fixed filter_input() bug - now actually sanitizes POST data
  • ✅ Logs XSS attempts to application/logs/ with user ID, IP, timestamp, affected fields
  • ✅ Bypasses password fields: user_password, user_passwordv
  • ✅ Bypasses HTML fields: email_template_body
  • ✅ Recursive array sanitization
  • ✅ Kept output encoding (defense-in-depth)

Strategy:

  • Input: xss_clean() + strip_tags() (removes dangerous content)
  • Output: htmlsc() (prevents any remaining XSS)
  • No double-encoding: avoided html_escape() at input

All 13 controllers calling filter_input() now protected with logging.

...

Added in commit 8d0906f:

Additional password field bypasses:

  • invoice_password - Invoice PDF password protection
  • quote_password - Quote PDF password protection

Complete bypass list now includes:

  • user_password, user_passwordv (user accounts)
  • invoice_password (invoices)
  • quote_password (quotes)
  • email_template_body (HTML content)

All password fields can now contain special characters like "'> without sanitization.

Applied all code review suggestions in commit 6bfaa47:

Changes made:

  • ✅ Optimized XSS logging: Moved ip_address and user_agent to request level (reduces log size, improves readability)
  • ✅ JSON encoding already has security flags: JSON_HEX_TAG | JSON_HEX_AMP | JSON_HEX_APOS | JSON_HEX_QUOT
  • ✅ Strict comparison already applied: in_array(..., true) prevents type juggling
  • ✅ JSON error handling already implemented: Falls back to print_r() if encoding fails

All suggestions from the review thread have been addressed.
