{"cve":"CVE-2026-7648","nvd":{"published":"2026-05-14T05:16:46.080","modified":"2026-06-17T11:02:44.097","status":"Deferred","description":"The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to payment bypass through user-controlled key in all versions up to, and including, 4.3.5. This is due to improper handling of user-supplied request parameters in the REST API endpoint, which passes the unsanitized parameter array to the add_to_cart() function where array_merge() allows attacker-controlled values to overwrite hardcoded defaults. This makes it possible for authenticated attackers, with subscriber-level access and above, to enroll in any paid course entirely free of charge by supplying a quantity value of zero, which causes the order total to calculate as $0 and bypasses all payment gateway requirements.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/learnpress/tags/4.3.3/inc/cart/class-lp-cart.php#L105","https://plugins.trac.wordpress.org/browser/learnpress/tags/4.3.3/inc/cart/class-lp-cart.php#L180","https://plugins.trac.wordpress.org/browser/learnpress/tags/4.3.3/inc/rest-api/v1/frontend/class-lp-rest-courses-controller.php#L474","https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/cart/class-lp-cart.php#L105","https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/cart/class-lp-cart.php#L180"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-7648","score":0.00423,"percentile":0.36638,"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).
