CVE-2025-31878Network attack vector

Subscriber-level settings changes via missing capability check

Published Apr 1, 2025 · Updated Apr 28, 2026

Missing authorization in UPC/EAN/GTIN Barcode Generator/Importer 2.0.2 and earlier allows remote authenticated users to change plugin settings. An exposed settings-update function omits the WordPress capability check before accepting and saving submitted configuration values. Subscriber-level access is sufficient, and unauthorized configuration changes can alter plugin behavior and interrupt barcode operations.
