Impact

The vulnerability is an improper neutralization of input during web page generation that allows stored cross‑site scripting. Malicious script code submitted through the WordPress WCFM Marketplace plugin is retained and executed whenever a user views the affected content, potentially allowing arbitrary script execution in the victim’s browser.

Affected Systems

The issue affects the WC Lovers WCFM Marketplace plugin for WordPress, including all releases up to and including version 3.8.3.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity. No EPSS score is available and the vulnerability is not listed in CISA KEV. The likely attack vector is a web‑based stored XSS that does not require special privileges; an attacker only needs the ability to inject data that will be rendered in a user’s browser.
