CVE-2024-50421Network attack vector

Unauthenticated debug activation via missing capability check

Published Oct 29, 2024 · Updated Apr 28, 2026

Missing authorization in WP Overnight PDF Invoices & Packing Slips for WooCommerce 3.8.6 and earlier allows remote attackers to enable debug output. The Main::enable_debug() method enables PHP error reporting and display without first verifying that the requester can manage plugin settings. An unauthenticated request can therefore activate error display when the plugin's debug setting is enabled, changing PHP's per-request diagnostics without reported data modification or service interruption.
