The Cost of Goods: Product Cost & Profit Calculator for WooCommerce plugin for WordPress suffers from a reflected cross-site scripting vulnerability (CWE-79) in the 'section' parameter. This vulnerability arises from improper neutralization of input during web page generation, allowing unauthenticated attackers to inject and execute arbitrary web scripts if a user interacts with a maliciously crafted link. The issue affects all plugin versions up to 3.2.8. The CVSS 3.1 base score is 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, scope changed, and low impact on confidentiality and integrity with no impact on availability. No known exploits in the wild or official patches have been reported.

Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the context of a victim's browser session when the victim clicks a crafted link. This can lead to limited confidentiality and integrity impacts, such as theft of sensitive information or manipulation of displayed content. There is no impact on system availability. The vulnerability requires user interaction and affects the security scope beyond the vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
