Summary
The PDF Invoice for WooCommerce plugin (with its Drag and Drop Template Builder) for WordPress-based online stores is affected. A flaw in how it handles checkout notes lets an unauthenticated visitor run arbitrary code on the affected website's server, potentially giving them full control of the site and its data.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
The PDF Invoice for WooCommerce + Drag and Drop Template Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 7.1.1 via the 'customer_note' parameter parameter. This is due to insufficient sanitization of the customer_note checkout field, which is inlined verbatim into invoice HTML, entity-decoded back into a live tag by simplehtmldom, reassembled into raw bytes by mPDF, and passed to unserialize() in _getObjAttr without validation. This makes it possible for unauthenticated attackers to execute code on the server. An unauthenticated attacker can trigger the vulnerable code path on a default install by placing an anonymous WooCommerce checkout via the public Store API (POST /wc/store/v1/checkout) using a Direct Bank Transfer or cheque payment method, which automatically transitions the order to 'on-hold' status and fires the plugin's invoice-generation hook.
