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."}],"title":"FlexStock <= 3.17.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'post_content' Parameter via REST update endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b03cabc6-1cbe-4aa2-8eae-cea30d01b811?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/models/class-product.php#L1500"},{"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-api.php#L577"},{"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-api.php#L79"},{"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-hooks.php#L1184"},{"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-app.php#L458"},{"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/helper/functions.php#L139"},{"url":"https://plugins.trac.wordpress.org/changeset/3768111/stock-sync-with-google-sheet-for-woocommerce/trunk/includes/models/class-product.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Morato Antoine"}],"timeline":[{"time":"2026-10-12T16:38:03.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T21:11:02.000Z","lang":"en","value":"Disclosed"}]}}}
