This is due to a logic flaw involving the inconsistent use of parameters during the cart addition process. The plugin uses the parameter 'product_tmp_two' for computing a security hash against price tampering while using 'wspsc_product' to display the product, allowing an unauthenticated attacker to substitute details from a cheaper product and bypass payment for a more expensive item.","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:H/A:N","score":7.5},"cwes":["CWE-472"],"references":["https://plugins.trac.wordpress.org/browser/wordpress-simple-paypal-shopping-cart/tags/5.1.2/wp_shopping_cart.php#L156","https://plugins.trac.wordpress.org/browser/wordpress-simple-paypal-shopping-cart/tags/5.1.2/wp_shopping_cart.php#L165","https://plugins.trac.wordpress.org/browser/wordpress-simple-paypal-shopping-cart/tags/5.1.2/wp_shopping_cart.php#L171","https://plugins.trac.wordpress.org/browser/wordpress-simple-paypal-shopping-cart/tags/5.1.2/wp_shopping_cart.php#L261","https://plugins.trac.wordpress.org/changeset/3275373/"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-3530","score":0.0054,"percentile":0.45451,"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).
