{"id":"CVE-2025-3530","state":"PUBLISHED","title":"WordPress Simple PayPal Shopping Cart <= 5.1.2 - Unauthenticated Product Price Manipulation","description":"The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to product price manipulation in all versions up to, and including, 5.1.2. 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.","publishedAt":"2025-04-23T07:06:49.749Z","updatedAt":"2026-04-08T17:28:46.040Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["mra13 Simple Shopping Cart"],"affected":[{"vendor":"mra13","product":"Simple Shopping Cart","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.1.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e0a3910b-adc4-4633-a6a1-32ba50894be4?source=cve","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#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#L261","https://www.tipsandtricks-hq.com/wordpress-simple-paypal-shopping-cart-plugin-768","https://plugins.trac.wordpress.org/changeset/3275373/"],"weaknesses":["CWE-472"],"ingestedAt":"2026-10-29T20:09:09.358Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/3xxx/CVE-2025-3530.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-3530","state":"PUBLISHED","datePublished":"2025-04-23T07:06:49.749Z","dateUpdated":"2026-04-08T17:28:46.040Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-04-11T22:18:57.487Z"},"containers":{"cna":{"title":"WordPress Simple PayPal Shopping Cart <= 5.1.2 - Unauthenticated Product Price Manipulation","descriptions":[{"lang":"en","value":"The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to product price manipulation in all versions up to, and including, 5.1.2.
