Published Jan 24, 2024 · Updated Apr 28, 2026

Arbitrary file upload in UkrSolution Barcode Scanner with Inventory & Order Manager 1.5.1 and earlier allows remote attackers to write files. The uploadFile function accepts attacker-supplied files without validating their type, permitting dangerous content to be stored on the WordPress server. No authentication or user interaction is required, and a server-executable upload can enable remote code execution in the site's security context.
