DescriptionCVE.org

The WCPOS - Point of Sale (POS) plugin for WooCommerce plugin for WordPress is vulnerable to Code Injection via the 'thermal' Template Engine in all versions up to, and including, 1.9.14 due to the Receipt_Renderer_Factory dispatching templates with the 'thermal' engine to the Legacy_Php_Renderer instead of a safe thermal-specific renderer. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to inject arbitrary PHP code into a template post that is subsequently written to a temporary file and executed via PHP's include(), resulting in remote code execution on the server. This requires the attacker to have Shop Manager-level access or above, as the template save path enforces a wcpos_template_settings nonce and the manage_woocommerce_pos capability check.

AnalysisAI

Remote code execution in the WCPOS Point of Sale plugin for WordPress/WooCommerce (all versions through 1.9.14) allows authenticated Shop Manager-level users to inject and execute arbitrary PHP on the server. The flaw lies in Receipt_Renderer_Factory incorrectly routing 'thermal' engine templates to Legacy_Php_Renderer, which writes attacker-controlled content to a temporary file and executes it via PHP's include(). …
