This release focuses on operational reliability, security hardening, and campaign monitoring capabilities.

• 🚀 Stuck Campaign Detector - Automated detection and recovery system for stuck campaigns with webhook notifications
• 🔒 Security Enhancements - Password change validation and XSS prevention measures
• ✉️ Journey Email Reliability - Fixed critical Reply-To validation issues preventing email delivery

🚀 Major Features

Stuck Campaign Detector (#1500)

A comprehensive automated system for detecting and managing campaigns that stop progressing due to worker failures.

Key Capabilities:

• Automated Detection: Cron job running every 5 minutes detects campaigns in 'Sending' status that have stopped progressing
• Detection Criteria:
• No workers processing pending batches
• All workers silent (LastPingedAt > 60 seconds)
• Worker assignment lost (Working batches with no ProcessID)
• Webhook Notifications: Real-time alerts with 30-minute cooldown to prevent spam
• HMAC-SHA256 signature support for security
• Comprehensive payload with campaign details and stuck reason
• Admin UI Management:
• "Stuck Campaigns" filter to view all stuck campaigns (always visible, no date filtering)
• "Unstuck" action to reset stuck batches to Pending status
• "Mark as Failed" action to cancel stuck campaigns
• Audit Trail: Complete logging in oempro_stuck_campaigns_log table with resolution tracking

Configuration:

STUCK_CAMPAIGN_DETECTOR_ENABLED=true
STUCK_CAMPAIGN_WEBHOOK_URL=
STUCK_CAMPAIGN_WEBHOOK_HMAC_SECRET=
STUCK_CAMPAIGN_NOTIFICATION_COOLDOWN_MINUTES=30

Database Migration Required:

docker exec oempro_app bash -c "cd /var/www/html/cli/ && php5.6 dbmigrator.php migrate"

Enhanced Email Sending with Comprehensive Validation

Improved email sending reliability with strict validation and error handling for journey emails.

Improvements:

• From Email Validation: Validates From email before API calls to catch issues early
• Trimming & Validation: Applied to all email fields (From, Reply-To, CC, BCC)
• Smart Reply-To Handling: Skips Reply-To field if personalization returns invalid email
• Enhanced Error Logging: Includes actual email addresses in error context for easier debugging

Impact: Prevents email sending failures at the API layer and provides clear diagnostic information.

Version 5.7.3 Upgrade Function

Automated upgrade process for smooth version transitions.

🐛 Bug Fixes

Critical Fixes

Journey Email Reply-To Validation Errors (#1497)

Problem: Journey emails failing with "Reply-To email address is invalid" errors.

Root Cause: Journey action parameters contained email addresses with trailing whitespace (e.g., "support@example.com "), which failed filter_var() validation.

Solution:

• Add trim() to all personalized email fields (From, Reply-To, CC, BCC)
• Validate Reply-To before including in API request
• Skip Reply-To entirely if personalized email is empty or invalid
• Enhanced error logging with actual email addresses for debugging

Impact: All journey emails with Reply-To addresses containing trailing whitespace can now send successfully.

Installation Theme and Permission Issues

Problem: Fresh installations failing with theme errors and permission issues.

Fixes:

• Resolved theme selection errors during installation
• Fixed file and directory permission issues
• Improved installation script robustness

UI/UX Fixes

Campaign Report Chart Overlap (#1494)

Problem: Campaign statistics chart overlapping with "Scheduled" link, making it unclickable.

Solution: Adjusted chart positioning to prevent overlap with navigation elements.

Invalid Custom Fields During Subscription (#1503)

Problem: Invalid custom field values causing subscription failures.

Solution:

• Validate custom fields during subscription process
• Skip invalid custom fields instead of failing the entire subscription
• Log warnings for invalid fields for admin review

Campaign Report Empty State Improvements (#1504, #1496)

Problem:

• "CREATE CAMPAIGN" button appearing in admin campaign report (admins shouldn't create campaigns)
• Octeth Plug-Ins page showing confusing empty state

Solutions:

• Removed CREATE CAMPAIGN button from admin campaign report empty state
• Improved Octeth Plug-Ins empty state messaging
• Updated plugin repository links to point to correct locations

✨ Enhancements & Improvements

Performance Optimization

Composite Index for Link Click Deduplication (#1501)

Added database index to improve link click statistics query performance.

Technical Details:

• Created composite index on oempro_link_stats table: (RelCampaignID, SubscriberID, LinkID)
• Optimizes deduplication queries for campaign link click reporting
• Reduces query execution time for large campaigns

Developer Tools

MySQL Slow Query Log Analysis (#1502)

New CLI command for analyzing MySQL slow query log.

Usage:

./cli/octeth.sh mysql:slow-log
./cli/octeth.sh mysql:slow-log --lines=100

Features:

• View slow queries directly from CLI
• Configurable number of lines to display
• Helps identify performance bottlenecks

Enhanced Log Management (#1499)

Improved logs:reset command to include additional log files.

Now Includes:

• Daily error logs from data/logs/
• MySQL slow query log
• Existing log files (queue logs, supervisor logs, etc.)

Usage:

./cli/octeth.sh logs:reset

UI/UX Improvements

Campaign Report UI Enhancements (#1495)

Improvements:

• Better scheduled campaign display and organization
• Improved campaign metrics visibility
• Enhanced empty state messaging
• Increased column widths for Recipients/Delivered and Open/Click Rate columns for better readability

🔒 Security Improvements

Current Password Requirement for Password Changes (#1498)

Enhancement: Added current password validation when users change their passwords.

Security Benefits:

• Prevents unauthorized password changes if session is compromised
• Follows security best practices for password management
• Protects user accounts from session hijacking scenarios

Implementation:

• Users must enter current password before setting new password
• Server-side validation of current password
• Clear error messages for failed validation

XSS Prevention in DatePreset Parameter

Vulnerability: DatePreset parameter lacked input validation, potential XSS vector.

Fix:

• Implemented whitelist validation for DatePreset values
• Only allows predefined safe values (e.g., "today", "yesterday", "last7days", "last30days", "thismonth", "lastmonth")
• Rejects any unexpected or malicious input

Impact: Prevents potential cross-site scripting attacks via URL parameters.
