WordPress Primer MyData for Woocommerce plugin < 4.2.4 - Reflected Cross Site Scripting (XSS) vulnerability

Published Apr 1, 2025 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed

Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in primersoftware Primer MyData for Woocommerce primer-mydata allows Reflected XSS.This issue affects Primer MyData for Woocommerce: from n/a through < 4.2.4.

Analysis

Technical impact

The vulnerability is an improper neutralization of input that allows an attacker to inject malicious script into a reflected response. A victim who visits a crafted URL can have arbitrary client‑side code executed in their browser, leading to session hijacking, cookie theft, or defacement. The weakness is a classic reflected XSS (CWE‑79) and can affect any user able to complete the request.

Affected Systems

The flaw exists in Primer MyData for WooCommerce plugin versions earlier than 4.2.4. Any WordPress site that has the plugin installed and running one of those versions is susceptible. The plugin developer is primersoftware and distributors should contact them for an update.

Risk and Exploitability

The CVSS base score of 7.1 classifies the issue as high severity. The EPSS score is under 1%, indicating a low but non‑zero exploitation probability, and the vulnerability is not yet listed in CISA KEV. Attackers can trigger the flaw by sending a malicious link to an unsuspecting user; once the victim clicks, the script is executed. The lack of server‑side validation or output sanitization is the fundamental failure.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
