CVE-2025-3530
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-3530 is a high-severity External Control of Assumed-Immutable Web Parameter (CWE-472) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to product price manipulation in all versions up to and including 5.1.2. The flaw stems from inconsistent parameter handling during cart addition, where the plugin computes a security hash using the 'product_tmp_two' parameter but displays product details via 'wspsc_product', enabling tampering that bypasses intended price validation. This is tracked as CWE-472 with a CVSS 3.1 score of 7.5.
An unauthenticated attacker can exploit the issue over the network by substituting details from a lower-priced product into the cart process, allowing them to purchase higher-value items without paying the correct amount and achieving integrity impact without requiring user interaction or privileges.
The referenced changeset on the WordPress plugin trac indicates that a fix has been applied in a subsequent release, so site administrators should update the plugin to a version beyond 5.1.2 to address the parameter inconsistency.
EPSS for this CVE rose from a low baseline to a peak of 0.0118 on 2026-02-17 before receding to the current value of 0.0014, indicating a period of increased exploitation interest after disclosure.

Vulnerability Data
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.…
more
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.

Secure coding standards require server-side verification of client-supplied data, eliminating the root cause of external control of immutable parameters.
Security testing in development and acceptance will detect parameter tampering vulnerabilities before deployment.
Secure development lifecycle mandates input validation and integrity checks that directly prevent external tampering of assumed-immutable parameters.
Application security requirements explicitly call for validation of all inputs, including hidden fields, mitigating CWE-472.
