{"cve":"CVE-2026-12126","nvd":{"published":"2026-07-11T07:16:45.633","modified":"2026-07-13T16:59:13.647","status":"Deferred","description":"The WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Attachment 'post_title' in all versions up to, and including, 3.7.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Vendor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An attacker can plant the payload by uploading a media attachment with a crafted title via the WordPress REST API (/wp-json/wp/v2/media), without ever invoking the AJAX endpoint themselves, as the unescaped title is later emitted inside DataTables JSON and inserted as innerHTML upon any privileged user loading the media dashboard.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/wc-multivendor-marketplace/tags/3.7.2/controllers/media/wcfmmp-controller-media.php#L120","https://plugins.trac.wordpress.org/browser/wc-multivendor-marketplace/tags/3.7.2/controllers/media/wcfmmp-controller-media.php#L58","https://plugins.trac.wordpress.org/browser/wc-multivendor-marketplace/tags/3.7.2/core/class-wcfmmp-media.php#L163","https://plugins.trac.wordpress.org/browser/wc-multivendor-marketplace/tags/3.7.3/controllers/media/wcfmmp-controller-media.php#L120","https://plugins.trac.wordpress.org/browser/wc-multivendor-marketplace/tags/3.7.3/controllers/media/wcfmmp-controller-media.php#L58"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-12126","score":0.00357,"percentile":0.2946,"date":"2026-11-01"},"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).
