{"affected":[],"cveId":"CVE-2026-107711","cwes":["CWE-79"],"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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.4,"severity":"medium","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793557026533,"publishedAt":1793441797370,"references":[{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-api.php#L577"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-api.php#L79"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-app.php#L458"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/classes/class-hooks.php#L1184"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/helper/functions.php#L139"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/stock-sync-with-google-sheet-for-woocommerce/tags/3.17.2/includes/models/class-product.php#L1500"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3768111/stock-sync-with-google-sheet-for-woocommerce/trunk/includes/models/class-product.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b03cabc6-1cbe-4aa2-8eae-cea30d01b811?source=cve"}],"remediation":[],"revision":"257f1f6f4e1ee69898fa0098552aab62cc36e20ca255fa27b45571fc326b052c","sources":[{"modifiedAt":1793557026533,"name":"NVD","retrievedAt":1793578557623,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107711"}],"ssvc":{"assessedAt":1793554430078,"automatable":"no","exploitation":"none","source":"NVD SSVC: 134c704f-9b21-4f2e-91b3-4a467353bcc0","technicalImpact":"partial"},"status":"published","title":"CVE-2026-107711","updatedAt":1793578557623}
