CVE-2026-107711
Description
The FlexStock – Product Stock Sync with Google Sheets for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'products[].post_content' parameter in all versions up to, and including, 3.17.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by any Subscriber-level user because the plugin's admin_enqueue_scripts callback exposes the REST bearer token in the Dashboard page source via wp_localize_script() without a capability check, and the REST endpoint's permission_callback validates only that bearer token rather than performing a current_user_can() capability check.
