{"cve":"CVE-2026-6176","nvd":{"published":"2026-08-28T16:18:21.580","modified":"2026-08-28T20:19:39.470","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-79"],"references":["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/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/trunk/includes/reviews/class-cr-endpoint.php#L445","https://plugins.trac.wordpress.org/changeset/3510305/"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-6176","score":0.00419,"percentile":0.36203,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
