{"id":"CVE-2026-6176","state":"PUBLISHED","title":"Customer Reviews for WooCommerce <= 5.106.0 - Unauthenticated Stored Cross-Site Scripting via Aggregated Review Form","description":"The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the aggregated review form submission in versions up to and including 5.106.0. This is due to insufficient input sanitization and output escaping on user-supplied review comment text. The plugin accepts review submissions from unauthenticated users through the 'cr_local_forms_submit' AJAX action without sanitizing HTML content before storing it via wp_insert_comment(), and later renders this stored content on product pages through comment_text() without proper escaping. This makes it possible for unauthenticated attackers with a valid review form URL (obtainable through review reminder emails sent to customers who placed orders) to inject arbitrary web scripts in pages that will execute whenever a user accesses the affected product page.","publishedAt":"2026-08-28T11:29:29.483Z","updatedAt":"2026-08-28T15:59:10.529Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["ivole Customer Reviews for WooCommerce"],"affected":[{"vendor":"ivole","product":"Customer Reviews for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.106.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d784afb0-03ca-48f8-ac21-230601c028a1?source=cve","https://plugins.trac.wordpress.org/browser/customer-reviews-woocommerce/trunk/includes/reviews/class-cr-endpoint.php#L445","https://plugins.trac.wordpress.org/browser/customer-reviews-woocommerce/tags/5.105.0/includes/reviews/class-cr-endpoint.php#L445","https://plugins.trac.wordpress.org/browser/customer-reviews-woocommerce/trunk/includes/reminders/class-cr-local-forms-ajax.php#L50","https://plugins.trac.wordpress.org/browser/customer-reviews-woocommerce/tags/5.105.0/includes/reminders/class-cr-local-forms-ajax.php#L50","https://plugins.trac.wordpress.org/changeset/3510305/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6176.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6176","state":"PUBLISHED","datePublished":"2026-08-28T11:29:29.483Z","dateUpdated":"2026-08-28T15:59:10.529Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-13T01:39:57.560Z"},"containers":{"cna":{"title":"Customer Reviews for WooCommerce <= 5.106.0 - Unauthenticated Stored Cross-Site Scripting via Aggregated Review Form","descriptions":[{"lang":"en","value":"The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the aggregated review form submission in versions up to and including 5.106.0.
