CVE-2026-107750 · Severity: high · CVSS 7.2 · Published 2026-10-31

A WordPress plugin for generating PDF invoices and packing slips is vulnerable to stored cross-site scripting attacks that allow unauthenticated attackers to inject malicious scripts. When an attacker submits specially crafted input through billing address or customer note fields, the malicious code is saved to the database and executes in the browsers of all users who later view the affected pages, potentially leading to account compromise, data theft, or unauthorized actions.

## Technical details

The plugin fails to properly sanitize and escape user input in billing_address fields (first_name, last_name, company) and customer_note parameters. The vulnerability is a bypass of an incomplete fix for CVE-2026-92244: the wp_kses() allowlist blocks literal angle brackets but passes through entity-encoded payloads (e.g., <img onerror=…>) that are decoded after the filter, allowing script injection. Unauthenticated attackers can inject arbitrary JavaScript that persists in the database and executes whenever users access pages with the injected data.
