{"cve":"CVE-2026-119166","nvd":{"published":"2026-10-31T07:16:36.750","modified":"2026-10-31T07:16:36.750","status":"Received","description":"The Welcart e-Commerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.12.5 via the 'member[ID]' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to overwrite any existing Welcart shop-member account's email address and password by supplying that member's numeric ID, then authenticate as that member to achieve full account takeover. The only authentication barrier is a wp_verify_nonce() check against a nonce printed to every unauthenticated visitor on the auto-published New Enrollment Form, meaning no existing account, no WordPress login, and no non-default configuration is required to exploit this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-287"],"references":["https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L3848","https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L4470","https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L5070","https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L5509","https://plugins.trac.wordpress.org/changeset/3760784/usc-e-shop"],"products":[],"source":"nvd","synced_at":"2026-10-31T07:31:41.930515885+00:00"},"epss":null,"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).
